Automated description from the Alliance of Genome Resources
Exhibits alpha-catenin binding activity; beta-catenin binding activity; and cadherin binding activity. Involved in several processes, including nervous system development; positive regulation of polarized epithelial cell differentiation; and regulation of postsynaptic neurotransmitter receptor internalization. Localizes to several cellular components, including the basolateral plasma membrane; early endosome; and glutamatergic synapse. Orthologous to human NUMB (NUMB endocytic adaptor protein).
