Apbb1 - amyloid beta (A4) precursor protein-binding, family B, member 1

Enables ubiquitin protein ligase binding activity. Involved in several processes, including double-strand break repair; positive regulation of DNA repair; and smooth muscle contraction. Acts upstream of or within several processes, including generation of neurons; negative regulation of neuron differentiation; and visual learning. Located in cytoplasm and nucleus. Is active in Schaffer collateral - CA1 synapse; glutamatergic synapse; and neuromuscular junction. Is expressed in several structures, including alimentary system; genitourinary system; integumental system; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in Alzheimer's disease. Orthologous to human APBB1 (amyloid beta precursor protein binding family B member 1).
