Protein attributes

Sequence length	268 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Transcriptional repressor. Involved in the generation and migration of neural crest cells.
Subcellular location	Nucleus Probable.
Tissue specificity	Expressed in placenta and adult heart, pancreas, liver, kidney and skeletal muscle.
Involvement in disease	Defects in SNAI2 are a cause of neural tube defects (NTD). Ref.2 Defects in SNAI2 are the cause of Waardenburg syndrome type 2D (WS2D) [MIM:608890]. WS2 is a genetically heterogeneous, autosomal dominant disorder characterized by sensorineural deafness, pigmentary disturbances, and absence of dystopia canthorum. The frequency of deafness is higher in WS2 than in WS1. Ref.6
Sequence similarities	Belongs to the snail C2H2-type zinc-finger protein family. Contains 5 C2H2-type zinc fingers.
