Maz | Myc-associated zinc finger protein; Transcriptional activator that binds to purine-rich GAGA sites found in the promoter of many genes including insulin I and II and islet amyloid polypeptide. (477 aa) | ||||
Sf3b4 | Splicing factor 3B subunit 4; Involved in pre-mRNA splicing as a component of the splicing factor SF3B complex. SF3B complex is required for 'A' complex assembly formed by the stable binding of U2 snRNP to the branchpoint sequence (BPS) in pre-mRNA. Sequence independent binding of SF3A/SF3B complex upstream of the branch site is essential, it may anchor U2 snRNP to the pre-mRNA. May also be involved in the assembly of the 'E' complex. SF3B4 has been found in complex 'B' and 'C' as well. Belongs also to the minor U12-dependent spliceosome, which is involved in the splicing of rare class [...] (424 aa) |
