Trp63 | Tumor protein 63; Acts as a sequence specific DNA binding transcriptional activator or repressor. The isoforms contain a varying set of transactivation and auto-regulating transactivation inhibiting domains thus showing an isoform specific activity. May be required in conjunction with TP73/p73 for initiation of p53/TP53 dependent apoptosis in response to genotoxic insults and the presence of activated oncogenes. Involved in Notch signaling by probably inducing JAG1 and JAG2. Activates transcription of the p21 promoter (By similarity). Activates RIPK4 transcription. Plays a role in the [...] (680 aa) | ||||
Vpreb1 | Immunoglobulin iota chain; Associates with the Ig-mu chain to form a molecular complex that is expressed on the surface of pre-B-cells. This complex presumably regulates Ig gene rearrangements in the early steps of B- cell differentiation; Belongs to the immunoglobulin superfamily. (142 aa) |
