Ankyrin repeat and SAM domain-containing protein 4B

Gene

Anks4b

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

As part of the intermicrovillar adhesion complex/IMAC plays a role in epithelial brush border differentiation, controlling microvilli organization and length. Plays a role in assembly of the complex (By similarity). May play a role in cellular response to endoplasmic reticulum stress (PubMed:22589549).By similarity1 Publication

Interactioni

Subunit structurei

Part of the IMAC/intermicrovillar adhesion complex/intermicrovillar tip-link complex composed of ANKS4B, MYO7B, USH1C, CDHR2 and CDHR5 (By similarity). Interacts with USH1C; the interaction is direct and is required for ANKS4B localization to the tip of microvilli (PubMed:15461667, PubMed:26812017). Interacts with MYO7B; the interaction is direct (PubMed:26812017). May interact with HSPA5 (PubMed:22589549).By similarity3 Publications
