Snai3 - snail family zinc finger 3

Enables DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in negative regulation of transcription by RNA polymerase II. Acts upstream of or within regulation of transcription by RNA polymerase II. Located in nucleus. Part of transcription regulator complex. Is expressed in several structures, including 1st branchial arch; genitourinary system; hemolymphoid system gland; hepatic primordium; and lung. Orthologous to human SNAI3 (snail family transcriptional repressor 3). [provided by Alliance of Genome Resources, Apr 2022]
