Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Probably involved in connections of major cytoskeletal structures to the plasma membrane. In epithelial cells, required for the formation of microvilli and membrane ruffles on the apical pole. Along with PLEKHG6, required for normal macropinocytosis (By similarity).By similarity

Enzyme regulationi

A head-to-tail association, of the N-terminal and C-terminal halves results in a closed conformation (inactive form) which is incapable of actin or membrane-binding.By similarity

Note: Localization to the apical membrane of parietal cells depends on the interaction with MPP5. Microvillar peripheral membrane protein (cytoplasmic side) (By similarity). Localizes to cell extensions and peripheral processes of astrocytes. Colocalizes with EZR and SLC9A3R2 at the apical cell membrane of glomerular epithelium cells.By similarity2 Publications
