SNAI3 (Snail Family Transcriptional Repressor 3) is a Protein Coding gene. GO annotations related to this gene include transcription factor activity, sequence-specific DNA binding and copper ion binding. An important paralog of this gene is SNAI2. Seems to inhibit myoblast differentiation. Transcriptional repressor of E-box-dependent transactivation of downstream myogenic bHLHs genes. Binds preferentially to the canonical E-box sequences 5-CAGGTG-3 and 5-CACCTG-3 (By similarity).
