Enables chromatin binding activity; nucleic acid binding activity; and protein kinase binding activity. Predicted to be involved in negative regulation of mRNA polyadenylation; positive regulation of DNA-templated transcription, elongation; and positive regulation of transcription by RNA polymerase II. Predicted to act upstream of or within protein phosphorylation. Located in nucleus. Is expressed in several structures, including central nervous system; early embryo; gonad; hemolymphoid system gland; and limb. Orthologous to human CCNT1 (cyclin T1).
