Homo sapiens growth inhibitor p33ING1 (ING1) mRNA, complete cds
Inhibitor of growth 1
Inhibitor of growth family member 1
Inhibitor of growth protein 1
Tumor suppressor ING 1
Tumor suppressor ING1
Cooperates with p53/TP53 in the negative regulatory pathway of cell growth by modulating p53-dependent transcriptional activation. Implicated as a tumor suppressor gene.
Isoform 2 was expressed in all normal tissues and cells examined, as well as in all breast cancer and melanoma cell lines examined. Isoform 3 was expressed in testis, liver, and kidney, weakly expressed in colon and brain and not expressed in breast and cultured melanocytes. Isoform 4 was highly expressed in testis and weakly expressed in brain, but not expressed in breast, colon, kidney, melanocytes, breast cancer or melanoma cell lines.
Defects in ING1 are a cause of head and neck squamous cell carcinomas (HNSCC) [MIM:275355]; also known as squamous cell carcinoma of the head and neck.
Belongs to the ING family. Contains 1 PHD-type zinc finger.
