pfam12886: TORC_C (This model is not part of the current CDD release)
Transducer of regulated CREB activity, C terminus
This family includes the C terminal region of TORC proteins. TORC (Transducer of regulated CREB activity) is a protein family of coactivators that enhances the activity of CRE-depended transcription via a phosphorylation-independent interaction with the bZIP DNA binding/dimerization domain of CREB (cAMP Response Element-Binding). The C terminus region is negatively charged, resembling the transcription activation domains. When this domain, from all three human TORC proteins, was expressed as fusion proteins with the DNA-binding domain of GAL4 (GAL4-BD), and tested for induction of a minimal promoter linked to GAL4-binding sites (UAS-GAL4), UAS-GAL4 was potently induced by GAL4-BD fusions containing the C-terminal portion of all three human TORCs.
