Calcium/phospholipid-binding protein that plays a role in the plasmalemma repair mechanism of endothelial cells that permits rapid resealing of membranes disrupted by mechanical stress. Involved in endocytic recycling. Implicated in VEGF signal transduction by regulating the levels of the receptor KDR. Binds Ca(2+). The ions are bound to the C2 1 domain. Interacts with EHD1 (PubMed:21177873). Interacts with EHD2; the interaction is direct (PubMed:21177873). Interacts with DNM2 and KDR (PubMed:21177873). Interacts with RIPOR2 (By similarity). Found at nuclear and plasma membranes. Enriched in undifferentiated myoblasts near the plasma membrane in puncate structures (By similarity). Concentrated at the membrane sites of both myoblast-myoblast and myoblast-myotube fusions. Detected at the plasmalemma in endothelial cells lining intact blood vessels. Expressed in myoblasts (at protein level). Expressed in endothelial cells. Up-regulated during myotube formation. The C2 1 domain associates with lipid membranes in a calcium-dependent manner. Mice lacking Myof display fewer large multinucleated myotubes and are impaired in their ability to regenerate skeletal muscle after injury. They display a defective membrane repair in endothelial cells. They show also a delayed endocytic recycling. Belongs to the ferlin family. Extended N-terminus.
