Predicted to enable several functions, including DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and protein N-terminus binding activity. Involved in several processes, including negative regulation of smooth muscle cell apoptotic process; negative regulation of smooth muscle cell migration; and positive regulation of smooth muscle cell proliferation. Located in nucleus. Part of protein-DNA complex. Human ortholog(s) of this gene implicated in Adams-Oliver syndrome and dilated cardiomyopathy. Orthologous to human RBPJ (recombination signal binding protein for immunoglobulin kappa J region). [provided by Alliance of Genome Resources, Apr 2022]
