Fam89b - family with sequence similarity 89, member B

Enables transcription corepressor binding activity. Involved in establishment of cell polarity; negative regulation of transmembrane receptor protein serine/threonine kinase signaling pathway; and positive regulation of cell migration. Located in cytoplasm and lamellipodium. Is expressed in several structures, including branchial arch; cranial ganglion; heart valve; medulla oblongata basal plate mantle layer; and sensory organ. Orthologous to human FAM89B (family with sequence similarity 89 member B). [provided by Alliance of Genome Resources, Apr 2022]
