Summary: Enables RNA polymerase II-specific DNA-binding transcription factor binding activity and transcription coactivator activity. Involved in several processes, including cytoplasmic streaming; positive regulation of cell population proliferation; and regulation of gene expression. Located in cytoplasm; endomembrane system; and lateral plasma membrane. Part of RNA polymerase II transcription regulator complex. Is expressed in several structures, including AB lineage cell; anus; germ line; neurons; and somatic nervous system. Used to study cancer and obesity. Human ortholog(s) of this gene implicated in several diseases, including Adams-Oliver syndrome; Alagille syndrome; Hajdu-Cheney syndrome; adult T-cell leukemia/lymphoma; and aortic valve disease 1. Orthologous to human NOTCH1 (notch receptor 1) and NOTCH2 (notch receptor 2). [provided by Alliance of Genome Resources, Jul 2025]

Zygotically expressed MOM-2 (Wnt) is responsible for two distinct cell-cell interactions as the MS blastomere produces one-third of the body wall muscles. Both the inhibitory and the activating interactions require precise spatiotemporal expression of zygotic MOM-2, which is dependent upon two distinct GLP-1 Notch signals.
Title: Reciprocal signaling by Wnt and Notch specifies a muscle precursor in the C. elegans embryo.
Study suggests that GLP-1 signaling is directly responsible for driving all stages of proliferation in the wild-type germline, and loss of its activity causes differentiation without intervening, distinctly regulated transit-amplifying divisions.
