Monoclonal Anti-ING1 antibody produced in mouse

Three alternatively spliced mRNAs of the gene ING1 (inhibitor of growth family member 1), p47ING1a, p33ING1b and p24ING1c, encode for proteins that function as growth inhibitors. The proteins are localized to the nucleus and they have a common C-terminal region. The major isoforms expressed in humans are p47ING1a and p33ING1b. The gene ING1 is mapped to human chromosome 13q34.

recombinant ING1.

The ING (inhibitor of growth) family of proteins is involved in several cellular processes, such as cell cycle, senescence and apoptosis. They activate acetylation-dependent pathways that in turn, regulate gene expression. The isoform p33ING1b is found to be involved in the regulation of apoptosis. Suppression of p33ING1b expression is found to promote the formation of tumor. On the other hand, increased expression arrests cells at G1 phase of the cell cycle and inhibits the progression of cell cycle. These processes are mediated by interactions with p53 tumor suppressor. Human ING1 proteins are found to be associated with proteins involved in histone acetyltransferase (HAT) activity, such as TRRAP (transformation/transcription domain associated protein), PCAF (P300/CBP-associated factor), CBP (cap binding protein), and p300. The isoform p47ING1a is found to inhibit histone acetylation and bind to histone deacetylase HDAC1 (histone deacetylase 1). The isoform p33ING1b regulates the association between proliferating cell nuclear antigen (PCNA) and p30 that is important for DNA repair and chromatin remodeling.
