Protein Structure

UniProt Annotation

Function

Essential regulator of neutrophil polarity. Regulates neutrophil polarization by regulating AKT1 phosphorylation through a mechanism that is independent of PIK3CG activity. {ECO:0000269PubMed:19897731}.

Subcellular Localization

Membrane {ECO:0000250}; Lipid-anchor {ECO:0000250}. Cell projection, stereocilium {ECO:0000269PubMed:16829577, ECO:0000269PubMed:17584769}. Note=Colocalizes with WHRN at stereocilium tip during hair cell development. Colocalizes with MPP5 in the retina, at the outer limiting membrane (OLM). Colocalizes with WHRN in the retina, at the outer limiting membrane (OLM), outer plexifirm layer (OPL), basal bodies, and at connecting cilium (CC). Colocalizes with NF2 in non-myelin-forming Schwann cells (By similarity). {ECO:0000250}.

Disease Associations

Tissue Specificity

Abundantly expressed in the erythrocytes (at protein level). {ECO:0000269PubMed:19897731}.
