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 . May play a role in cellular response to endoplasmic reticulum stress (By similarity).
Subcellular locations: Cell projection, Microvillus
Localizes at the tip of microvilli . May associate with endoplasmic reticulum membranes (By similarity).
Expressed in kidney and small intestine.
