Overview:

p33 ING1 is a tumor suppressor protein that can induce cell growth arrest and apoptosis. The encoded protein is a nuclear protein that physically interacts with the tumor suppressor protein TP53 and is a component of the p53-signaling pathway. Reduced expression and rearrangement of this gene have been detected in various cancers. Multiple alternatively spliced transcript variants encoding distinct isoforms have been reported.  The accession number listed below is for variant (4) that encodes the longest isoform (D).   Other synonyms for p33 ING1 include p33, p47, p33ING1, p24ING1c, p33ING1b, p47ING1a, growth inhibitor ING1, inhibitor of growth 1, tumor suppressor ING1 and growth inhibitory protein ING1.
