Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific; RNA polymerase II transcription regulatory region sequence-specific DNA binding activity; and protein domain specific binding activity. Involved in hair follicle development and regulation of chondrocyte differentiation. Acts upstream of or within several processes, including chondrocyte differentiation; negative regulation of transcription, DNA-templated; and positive regulation of extrinsic apoptotic signaling pathway via death domain receptors. Located in nucleus. Is expressed in several structures, including alimentary system; brain; genitourinary system; limb; and skin. Used to study trichorhinophalangeal syndrome type I. Human ortholog(s) of this gene implicated in osteochondrodysplasia; trichorhinophalangeal syndrome type I; and trichorhinophalangeal syndrome type III. Orthologous to human TRPS1 (transcriptional repressor GATA binding 1). [provided by Alliance of Genome Resources, Apr 2022]
