Eukaryotic translation initiation factor 1A, X-chromosomal (eIF1A) is a protein that in humans is encoded by the EIF1AX gene. (wikipedia.org)
This gene encodes an essential eukaryotic translation initiation factor. (wikipedia.org)
Elongation3
During the elongation phase three more factors namely EF Tu, EF Ts, and EF G are involved. (cbsetuts.com)
Translation proceeds in four phases: activation, initiation, elongation and termination (all describing the growth of the amino acid chain, or polypeptide that is the product of translation). (wikidoc.org)
Elongation occurs when the next aminoacyl-tRNA (charged tRNA) in line binds to the ribosome along with GTP and an elongation factor. (wikidoc.org)
MRNA2
In the mRNA from 5′ end to 3′ end all the codons together are messages from the gene and this message by way of translation is converted into a polypeptide chain. (cbsetuts.com)
Initiation involves the small subunit of the ribosome binding to 5' end of mRNA with the help of initiation factors (IF), other proteins that assist the process. (wikidoc.org)
Protein2
The protein is a component of the 43S pre-initiation complex (PIC), which mediates the recruitment of the small 40S ribosomal subunit to the 5' cap of messenger RNAs. (wikipedia.org)
Various protein factors regulate the process of translation. (cbsetuts.com)
Polypeptide2
In the last phase (Termination) again two factors namely RF1 and RF2 are needed to stop the synthesis of the polypeptide chain. (cbsetuts.com)
When this happens, no tRNA can recognize it, but releasing factor can recognize nonsense codons and causes the release of the polypeptide chain. (wikidoc.org)
Small1
The complete ribosome is required for translation to be continued, though in the process of initiation, the small ribosomal sub-unit (30S in the case of prokaryotes and 40S in the case of eukaryotes) only initiates the process. (cbsetuts.com)
Translation1
Note that there are 3 translation "windows" depending on where you start reading the code. (wikidoc.org)
Complex1
In E. coli cells at the initiation phase three initiation factors namely IF1, IF2, and IF3 promote the formation of the initiation complex. (cbsetuts.com)

Cryo-electron m3
Christian Spahn (Charité Medical University, Berlin, Germany) reported a cryo-electron microscopy reconstruction of ribosomes from Escherichia coli stalled in the decoding state with tRNA and elongation factor Tu at significantly improved resolution (less than 7 Å). (biomedcentral.com)
Bruno Klaholz (Institut de Génétique et de Biologie Moléculaire et Cellulaire (IGBMC), Strasbourg, France) reported a series of cryo-electron microscopy snapshots of prokaryotic ribosomal complexes directly visualizing either the mRNA structure blocked by repressor protein S15 or the unfolded, active mRNA. (biomedcentral.com)
In this study, we used gene editing and ribosomal profiling in combination with cryo-electron microscopy to establish that mitochondrial release factor 1 (mtRF1) detects noncanonical stop codons in human mitochondria by a previously unknown mechanism of codon recognition. (bvsalud.org)

Clearly, understanding the conformational dynamics of ribosomal initiation complexes is very important. (biomedcentral.com)

EIF21
The binding of Met-tRNAMet i to the small 40S ribosomal gaster eIF5B was reported to interact with the DEAD box subunit in eukaryotes is facilitated by factor eIF2. (nih.gov)
EIF5B3
Human eIF5B can functionally substitute for the yeast factor mote IF2 activities (reviewed in references 7, 18, 22, and 31. (nih.gov)
Consistent with an process in eukaryotes than in prokaryotes, and, as might be important role for GTP binding by eIF5B, mutations in the expected, a larger number of initiation factors are required in GTP-binding domain of human eIF5B impair translation in eukaryotes (27). (nih.gov)
An eIF5B/IF2 addition, ribosomal toe-printing assays revealed that eIF1A is homolog has also been identified in Archaea , and we found required for formation of a 48S preinitiation complex in which a 40S subunit with associated initiation factors and Met- that this protein can partially substitute for the yeast protein tRNAMet both in vivo and in vitro (25).

Ribosomes4
Mitochondrial translation initiation factor 3 (MTIF3) is a nuclear encoded protein required for the initiation of complex formation on mitochondrial ribosomes. (nih.gov)
One of us (M.R.) reported results from rapid kinetics techniques that show that the structure of the mRNA translation initiation region determines the timing of molecular events leading to formation of elongating 70S ribosomes from the 30S initiation complexes, which reveals a second control step in initiation in addition to formation of the 30S initiation complex. (biomedcentral.com)
Translation initiation is a much more complex ribosomes following subunit joining (33). (nih.gov)
In bacteria, release of newly synthesized proteins from ribosomes during translation termination is catalyzed by class-I release factors (RFs) RF1 or RF2, reading UAA and UAG or UAA and UGA codons, respectively. (bvsalud.org)
Subunit2
The protein is a component of the 43S pre-initiation complex (PIC), which mediates the recruitment of the small 40S ribosomal subunit to the 5' cap of messenger RNAs. (wikipedia.org)
Factor IF1 binds to the 30S subunit and protects the phenotype (11). (nih.gov)
Ribosome-recycl2
In prokaryotes, recycling requires the action of ribosome-recycling factor together with elongation factor G. In contrast, Tatyana Pestova (State University of New York, New York, USA) has found that in mammals recycling is achieved by a combination of the eukaryotic initiation factors (eIF) 3, 1, and 1A, which explains why a ribosome-recycling factor is not found in eukaryotic cells.

A proposed cause of ageing is the accumulation of epigenetic noise that disrupts gene expression patterns, leading to decreases in tissue function and regenerative capacity1-3. (harvard.edu)
Release factors1
Rachel Green (Johns Hopkins University, Baltimore, USA) showed that release factors make two distinct contributions to catalysis of peptidyl-tRNA hydrolysis - a relatively nonspecific activation of the catalytic center and specific selection of water as a nucleophile facilitated by a glutamine in the conserved GGQ motif in release factors.
