Summary
The protein encoded by this gene belongs to the highly conserved cyclin family, whose members are characterized by a dramatic periodicity in protein abundance through the cell cycle. Cyclins function as positive regulators of cyclin-dependent kinases (CDKs), and thereby play an essential role in the control of the cell cycle. Different cyclins exhibit distinct expression and degradation patterns, which contribute to the temporal coordination of each mitotic event. Studies of similar genes in chicken and drosophila suggest that this cyclin may associate with CDC2 and CDK2 kinases, and may be required for proper spindle reorganization and restoration of the interphase nucleus. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Oct 2011]

Vpr vpr The human Vpr interacting protein (hVIP/MOV34) is a likely cellular cofactor for HIV-1 Vpr inactivation of the cdc2-cyclin B kinase complex and induction of cell cycle arrest PubMed
vpr Data suggests that HIV-1 Vpr transactivation of the HIV-LTR promoter occurs through the inhibition of p300-associated cdc2-cyclin B kinase complex activity which enhances transcriptional activation by Rel A and p300 PubMed
vpr Inactivation of the cdc2-cyclin B kinase complex by HIV-1 Vpr leads to the activation of Poly(A) polymerase PubMed
vpr Inactivation of the cdc2-cyclin B kinase complex and arrest in the G2 phase of the cell cycle has been mapped to the C-terminus of HIV-1 Vpr, including amino acids 73, 80 and 84-96 PubMed
vpr HIV-1 Vpr inactivates the cdc2-cyclin B kinase complex by inactivating cdc25C, the phosphatase that dephosphorylates and activates cdc2 PubMed
vpr HIV-1 Vpr inactivates the cdc2-cyclin B kinase complex by inhibiting the dephosphorylation of cdc2 tyrosine 15, leading to arrest in the G2 phase of the cell cycle PubMed

NCBI Reference Sequences (RefSeq)

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
