Rabbit Anti-ING1/FITC Conjugated antibody
background:
This gene encodes 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. [provided by RefSeq].
Function:
Cooperates with p53/TP53 in the negative regulatory pathway of cell growth by modulating p53-dependent transcriptional activation. Implicated as a tumor suppressor gene.
Subcellular Location:
Nucleus.
Tissue Specificity:
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.
DISEASE:
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.
Similarity:
Belongs to the ING family.
Contains 1 PHD-type zinc finger.

肿瘤的发生是一个多基因参与,多步骤发生的复杂过程,抑癌基因的功能失活与癌基因的激活为其主要原因之一。 ING1基因是近期发现的抑癌基因,研究发现,它的过表达可抑制细胞生长、增殖,促进细胞凋亡,它的低表达与肿瘤的发生、发展有关。ING1正常时定位于胞核,发挥其诱导凋亡和调控细胞周期的作用,当其易位于胞质时上述作用逐步减弱或消失,在肿瘤发生时,多位于胞浆。
