Protein nameCyclin-L1
Protein functionInvolved in pre-mRNA splicing. Functions in association with cyclin-dependent kinases, CDKs, PubMed:18216018. Inhibited by the CDK-specific inhibitor CDKN1A/p21, PubMed:11980906. May play a role in the regulation of RNA polymerase II, pol II. May be a candidate proto-oncogene in head and neck squamous cell carcinomas, HNSCC, PubMed:12414649, PubMed:15700036. {ECO:0000269|PubMed:11980906, ECO:0000269|PubMed:12414649, ECO:0000269|PubMed:15700036, ECO:0000269|PubMed:18216018}.
Subcellular locationNucleus speckle {ECO:0000269|PubMed:18216018}. Nucleus, nucleoplasm {ECO:0000269|PubMed:18216018}. Note=Found in nuclear intrachromatin granules clusters, IGC, also called nuclear speckles, which are storage compartments for nuclear proteins involved in mRNA processing. {ECO:0000250}.
