Brain-specific angiogenesis inhibitor 1-associated protein 2 is a protein that in humans is encoded by the BAIAP2 gene.

Function

The protein encoded by this gene has been identified as a brain-specific angiogenesis inhibitor (BAI1)-binding protein. This interaction at the cytoplasmic membrane is crucial to the function of this protein, which may be involved in neuronal growth-cone guidance. This protein functions as an insulin receptor tyrosine kinase substrate and suggests a role for insulin in the central nervous system. This protein has also been identified as interacting with the dentatorubral-pallidoluysian atrophy gene, which is associated with an autosomal dominant neurodegenerative disease. It also associates with a downstream effector of Rho small G proteins, which is associated with the formation of stress fibers and cytokinesis. Alternative splicing of the 3'-end of this gene results in three products of undetermined function.

Interactions

BAIAP2 has been shown to interact with:

• ATN1,
• CDC42,
• EPS8,
• RAC1,
• SHANK1,
• WASF1, and
• WASF2.
