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) | ||||
Ube2q2 | Ubiquitin-conjugating enzyme E2 Q2; Accepts ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. In vitro catalyzes 'Lys-48'- linked polyubiquitination; Belongs to the ubiquitin-conjugating enzyme family. (378 aa) |
