Mouse Anti-HIF1 beta/FITC Conjugated antibody
background:
This metastasis suppressor gene product is a membrane glycoprotein that is a member of the transmembrane 4 superfamily. Expression of this gene has been shown to be downregulated in tumor progression of human cancers and can be activated by p53 through a consensus binding sequence in the promoter. Its expression and that of p53 are strongly correlated, and the loss of expression of these two proteins is associated with poor survival for prostate cancer patients. Two alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.
Function:
Required for activity of the Ah (dioxin) receptor. This protein is required for the ligand-binding subunit to translocate from the cytosol to the nucleus after ligand binding. The complex then initiates transcription of genes involved in the activation of PAH procarcinogens. The heterodimer with HIF1A or EPAS1/HIF2A functions as a transcriptional regulator of the adaptive response to hypoxia.
Subunit:
Efficient DNA binding requires dimerization with another bHLH protein. Forms a heterodimer with AHR, AHRR, HIF1A and EPAS1/HIF2A as well as with other bHLH proteins. Interacts with TACC3 (By similarity). Interacts with NOCA7. Heterodimer with HIF1A.
Subcellular Location:
Nucleus.
Similarity:
Contains 1 bHLH (basic helix-loop-helix) domain.
Contains 1 PAC (PAS-associated SLCterminal) domain.
Contains 2 PAS (PER-ARNT-SIM) domains.

转录调节因子(Transcriptin Regulators)
低氧诱导因子1β不仅对于机体在缺氧条件下维持正常的生理功能具有特别重要的意义,并在肿瘤的生长以及神经细胞凋亡等病理过程中起重要作用. HIF1β又称芳烃受体核转运蛋白1能调节许多下游基因的表达水平.
哺乳动物细胞在低氧压力条件下出现HIF。HIF是一种转录因子,对细胞的缺氧起稳定作用。
