ING1: Proteins and Enzymes

ING1 (Inhibitor of Growth 1; also p33^ING1b and ING1A) is a 32 kDa member of the ING family of tumor suppressors. It is very widely expressed, and participates in multiple cell functions. When bound to p53, ING1 inhibits cell growth; when complexed to GADD45, ING1 enhances DNA nucleotide excision repair; and when associated with HAT, ING1 promotes hyperacetylation of histones H3 and H4. Human ING1 is 279 amino acids (aa) in length. It contains a PIP-PBD region (aa 5 - 45), an NLS (aa 142 - 158), ...
