Protein Structure

UniProt Annotation

Function

F-actin cross-linking protein which is thought to anchor actin to a variety of intracellular structures. This is a bundling protein.

Subcellular Localization

Cytoplasm, cytoskeleton {ECO:0000269PubMed:7750553}. Cytoplasm, myofibril, sarcomere, Z line {ECO:0000269PubMed:7750553}. Cell membrane {ECO:0000250}. Cell junction {ECO:0000250}. Cell projection, ruffle {ECO:0000250}. Note=Colocalizes with MYOZ2 and PPP3CA at the Z- line of heart and skeletal muscle. Colocalizes with PSD in membrane ruffles and central reticular structures (By similarity). {ECO:0000250}.

Disease Associations

Bleeding disorder, platelet-type 15 (BDPLT15) [MIM:615193]: An autosomal dominant form of macrothrombocytopenia. Affected individuals usually have no or only mild bleeding tendency, such as epistaxis. Laboratory studies show decreased numbers of large platelets and anisocytosis, but the platelets show no in vitro functional abnormalities. {ECO:0000269PubMed:23434115}. Note=The disease is caused by mutations affecting the gene represented in this entry.
