Also known as: Sav; Salv; WW45; Wwp3; Wwp4; 1700040G09Rik
Summary: Predicted to enable several functions, including identical protein binding activity; signaling receptor binding activity; and signaling receptor complex adaptor activity. Acts upstream of or within several processes, including epithelial cell differentiation; hippo signaling; and negative regulation of cell population proliferation. Predicted to be located in cytosol and nucleus. Predicted to be active in cell-cell junction; cytoplasm; and dendrite. Is expressed in several structures, including genitourinary system; heart; liver; lung; and spleen. Used to study colonic disease and hepatocellular carcinoma. Orthologous to human SAV1 (salvador family WW domain containing protein 1). [provided by Alliance of Genome Resources, Apr 2022]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
