The actin protein is found in both the cytoplasm and the cell nucleus. (wikipedia.org)
DAZ family proteins are located in the nucleus and/or in the cytoplasm of male and female germ cells at different developmental stages throughout the gametogenesis. (ijbs.com)

In this complex, the claudin-like transmembrane protein HPO-30 recruits the WAVE regulatory complex (WRC) to dendrite branching sites, stimulating the Arp2/3 complex to polymerize actin. (stanford.edu)

Standards and samples are pipetted into the wells and anyTPM2 present is bound by the immobilized antibody. (abbkine.com)

The model, together with the structure of the G1-G3/actin complex, provide insight into the roles of putative PIP₂ -binding sites in both the N- and C-terminal halves of gelsolin. (ubc.ca)

Formins act as profilin-modulated processive actin nucleators conserved throughout a wide range of eukaryotes. (biomedcentral.com)
With the exception of ForI and ForC all other formins conform to the domain structure GBD/FH3-FH1-FH2-DAD, where DAD is the Diaphanous autoinhibition domain and GBD/FH3 is the Rho GTPase-binding domain/formin homology 3 domain that we propose to represent a single domain. (biomedcentral.com)
Formins are multidomain proteins conserved from plants to fungi and vertebrates. (biomedcentral.com)
Several users of actin nucleating protein formins reportedly regulate both AFs and MTs in vegetation16. (skinmicrobiomecongressca.com)

Nrf2 consists of six functional Neh domains (Neh1-Neh6), from which, the amino-terminal Neh2 domain controls binding Keap1-the inhibitor protein Kelch-like ECH-associated protein 1, that is responsible for the cytosolic sequestration of Nrf2 under physiological conditions (Fig. 2 a). (springer.com)

Vasodilator-stimulated phosphoprotein (VASP) is a member of the Ena-VASP protein family. (affbiotech.com)
Ena-VASP family members contain an EHV1 N-terminal domain that binds proteins containing E/DFPPPPXD/E motifs and targets Ena-VASP proteins to focal adhesions. (affbiotech.com)

Rhodamine phalloidin is a high-affinity F-actin probe conjugated to the red-orange fluorescent dye, tetramethylrhodamine (TRITC). (thermofisher.com)
Phalloidin is a bicyclic peptide belonging to a family of toxins isolated from the deadly Amanita phalloides 'death cap' mushroom and is commonly used in imaging applications to selectively label F-actin. (thermofisher.com)
Fluorescently-labeled phalloidin has virtually identical binding properties with actin from different species including plants and animals. (thermofisher.com)
Phalloidin binds F-actin with high selectivity while TRITC provides red-orange fluorescence of unparalleled brightness and photostability. (thermofisher.com)
Demonstrating very little nonspecific staining, Rhodamine phalloidin allows high-contrast discrimination of actin staining. (thermofisher.com)
Rhodamine phalloidin can be used to visualize and quantitate F-actin in tissue sections, cell cultures, or cell-free preparations. (thermofisher.com)

In addition, this protein binds with high affinity to fibronectin. (embl.de)

The alpha actins, found in muscle tissues, are a major constituent of the contractile apparatus. (wikipedia.org)
also called myosin heavy chain 95F (Mhc95F), or 95F MHC), which is a motor protein necessary for the morphogenesis of epithelial tissues during Drosophila development. (nih.gov)
encodes CARMIL, a large protein which is the most abundant in kidney and other epithelial tissues Tropanserin IC50 [1]. (insulin-receptor.info)
All other tissues appeared normal, suggesting that, in most cases, tensin's diverse functions are redundant and may be compensated for by other focal adhesion proteins. (ppbhg.org)

The localization of these fluorescent proteins was examined in living cells under a variety of conditions known to involve actin. (uconn.edu)
In phagocytosis of yeast, both proteins localize to the phagocytic cup but differ in localization to the internalized particle. (uconn.edu)
Surprisingly, the localization of the actin-binding domain GFP fusion protein precisely reflected that of their respective intact GFP fusion protein. (uconn.edu)
When expressed in a cell line lacking both ABP-120 and α-actinin, not only did the probes maintain their localization observed in wild type cells, the defective development program was rescued in cells expressing complete GFP fusion protein probes, suggesting the functionality of the fusion protein probes. (uconn.edu)
Dazl can regulate the expression, transport and localization of target mRNAs of proteins which control the differentiation, growth and maturation of germ cells. (ijbs.com)
