Nelfa | Negative elongation factor A; Essential component of the NELF complex, a complex that negatively regulates the elongation of transcription by RNA polymerase II (By similarity). The NELF complex, which acts via an association with the DSIF complex and causes transcriptional pausing, is counteracted by the P-TEFb kinase complex (By similarity). (530 aa) | ||||
Hif3a | Hypoxia-inducible factor 3-alpha; Acts as a transcriptional regulator in adaptive response to low oxygen tension. Acts as a regulator of hypoxia-inducible gene expression. Plays a role in the development of the cardiorespiratory system. [Isoform 2]: Attenuates the ability of transcription factor HIF1A, EPAS1 and the HIF1A-ARNT complex to bind to hypoxia-responsive elements (HRE) located within the enhancer/promoter of hypoxia- inducible target genes and hence inhibits HRE-driven transcriptional activation. Functions as an inhibitor of angiogenesis in hypoxic cells of the cornea. May ac [...] (664 aa) |
