LYVE1, also known as lymphatic vessel endothelial receptor 1 or lymphatic vessel endothelial hyaluronic acid receptor 1, is a member of the link protein family, which has the capability to bind with hyaluronic acid. (prospecbio.com)

Pex5p, the PTS1 receptor, is known to bind to the integral Pex13p and/or Pex17p and the peripheral Pex14p. (tcdb.org)
We can distinguish integral and peripheral proteins. (scienceasker.com)
The peripheral proteins are those that do not pass through the membrane. (scienceasker.com)

3M chromatography single use hybrid purifiers designed for soluble and insoluble impurities reduction using anion exchange chromatography in clarification of mAbs and other recombinant proteins. (3m.com.br)

Journal cover: V-ATPase is regulated by disassembly into soluble V 1 (shown in cyan) and membrane integral V o (shown in gold) subcomplexes. (upstate.edu)

3M's hybrid purifier incorporates anion exchange chromatography and membrane filtration to provide chromatographic clarification and mechanical separation by size. (3m.com.br)
The integral combination of the 0.2 micron rated membrane and anion exchange nonwoven provides robust reduction of insoluble particles well below 0.1 micron. (3m.com.br)

Pex4p is a membrane protein that may facilitate cycling of Pex5p back to the cytosol. (tcdb.org)
The ATP-dependent dislocation of the PTS1 receptor from the peroxisomal membrane into the cytosol is mediated by the AAA peroxins Pex1p and Pex6p ( Platta et al . (tcdb.org)
Most chloroplastic proteins are nuclear encoded, synthesized in the cytosol, and posttranslationally imported into the organelle. (silverchair.com)

We are interested in how the primary sequences of membrane proteins determine their three dimensional structures, and hence their functions. (yale.edu)
Here we revisit tau protein aggregation at primary, secondary, tertiary and quaternary structures. (ibecbarcelona.eu)
However, only a small number of structures of membrane proteins have been elucidated so far due to their low expression levels and the requirement of membrane mimetic environments for their study. (kent.ac.uk)

Upon prolonged high intracellular rises in Ca 2+ , platelets develop a procoagulant phenotype that is characterized by the surface membrane exposure of phosphatidylserine and by the inactivation of integrin α IIb β 3 (procoagulant platelet population) ( 5 ). (frontiersin.org)

Gastrointestinal absorption of soluble lead salts in adult humans can be high during fasting (40-50%), but is about 3-15% when ingested with food. (cdc.gov)

The 0 Å cross-linker CuCl 2 yields the reversible formation of disulfide bridge(s) between Toc64 and the established Toc complex subunits in purified outer envelope membranes. (silverchair.com)

The transcription of COX-1 yields a 2.7-kilobase (kb) messenger ribonucleic acid (mRNA) that encodes a 576-residue, 65-kd protein. (medscape.com)
Conversely, the transcription of COX-2 yields a 4.5-kb mRNA that encodes a 70-kd protein with roughly 70-75% homology to the COX-1 protein. (medscape.com)

We show that CCN1 (also known as CYR61), a matricellular protein that dampens and resolves liver fibrosis, also mediates cholangiocyte proliferation and ductular reaction, which are repair responses to cholestatic injury. (jci.org)

Endocytosis of GPI-linked membrane folate receptor-alpha. (rupress.org)

As such it was found to be located in soluble e. coli membranes that we were able to isolate by ultracentrifugation for in vitro testing. (europa.eu)
The quinol-fumarate reductase (QFR) respiratory complex of Escherichia coli is a four-subunit integral-membrane complex that catalyzes the final step of anaerobic respiration when fumarate is the terminal electron acceptor. (rcsb.org)

This type of protein was first encountered as ferredoxin, a reducing agent involved in nitrogen fixation and photosynthesis in plants before it was recognized to function in mt.E.T in animals. (biochemden.com)
Cytochrome a and a 3 possess and identical type of iron - porphyrin complex called "Heme.a",but their location to apo-protein are different. (biochemden.com)
