Sp3 | Transcription factor Sp3; Transcriptional factor that can act as an activator or repressor depending on isoform and/or post-translational modifications. Binds to GT and GC boxes promoter elements. Competes with SP1 for the GC-box promoters. Weak activator of transcription but can activate a number of genes involved in different processes such as cell-cycle regulation, hormone-induction and house-keeping (By similarity). (783 aa) | ||||
Sppl3 | Signal peptide peptidase-like 3; Intramembrane-cleaving aspartic protease (I-CLiP) that cleaves type II membrane protein substrates in or close to their luminal transmembrane domain boundaries. Acts like a sheddase by mediating the proteolytic release and secretion of active site- containing ectodomains of glycan-modifiying glycosidase and glycosyltransferase enzymes such as MGAT5, B4GAT1 and B4GALT1. Plays a role in the regulation of cellular glycosylation processes. Required to link T- cell antigen receptor (TCR) and calcineurin-NFAT signaling cascades in lymphocytes by promoting the [...] (384 aa) |
