Description

Predicted to enable microtubule binding activity. Predicted to be involved in several processes, including actin filament organization; positive regulation of neuron differentiation; and regulation of Rho protein signal transduction. Predicted to act upstream of or within several processes, including cell division; innate immune response; and nervous system development. Predicted to be located in several cellular components, including Golgi apparatus; bicellular tight junction; and spindle. Predicted to be active in cytoskeleton and ruffle membrane. Is expressed in several structures, including blood vessel; hindbrain neural plate; immature eye; mesoderm; and nervous system. Human ortholog(s) of this gene implicated in immunodeficiency 62 and neurodevelopmental disorder with midbrain and hindbrain malformations. Orthologous to several human genes including ARHGEF2 (Rho/Rac guanine nucleotide exchange factor 2).
