Homeobox protein Nkx-2.2

Gene

NKX2-2

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

Acts as a transcriptional activator. Required for the maintenance of NEUROD1 expression in the horomone-producing endocrine cells of the pancreas. May be involved in specifying diencephalic neuromeric boundaries, and in controlling the expression of genes that play a role in axonal guidance. Associates with chromatin at the NEUROD1 promoter region. Binds to a subset of consensus elements within the NEUROD1 promoter (By similarity).By similarity
