Cyclin A2 Recombinant Rabbit Monoclonal Antibody - BSA and Azide free [SD2052] (HA750288)

UNIPROT #

P20248

PROTEIN NAME

Cyclin A2

SYNONYMS

CCN1 antibody;CCNA antibody;Ccna2 antibody;CCNA2_HUMAN antibody;Cyclin A2 antibody;Cyclin-A antibody;Cyclin-A2 antibody

SEQUENCE SIMILARITIES

Belongs to the cyclin family. Cyclin AB subfamily.

DEVELOPMENTAL STAGE

Accumulates steadily during G2 and is abruptly destroyed at mitosis. Not detected during the G1 phase of the cell cycle. It accumulates during the DNA synthesis/S phase and disappears as cells progress into mitosis, between prophase and metaphase (at protein level).

POST-TRANSLATIONAL MODIFICATION

Polyubiquitinated via 'Lys-11'-linked ubiquitin by the anaphase-promoting complex (APC/C), leading to its degradation by the proteasome. Deubiquitinated and stabilized by USP37 enables entry into S phase.

SUBCELLULAR LOCATION

Nucleus, Cytoplasm.

FUNCTION

The critical role that the family of regulatory proteins known as cyclins play in eukaryotic cell cycle regulation is well established. The best-characterized cyclin complex is the mitotic cyclin B/Cdc2 p34 kinase, the active component of maturing promoting factor. Cyclin A accumulates prior to cyclin B in the cell cycle, appears to be involved in control of S phase and has been shown to associate with cyclin- dependent kinase-2 (Cdk2). In addition, cyclin A has been implicated in cell transformation and is found in complexes with E1A, transcription factors DRTF1 and E2F and retinoblastoma protein, p110. A second form of cyclin A, named cyclin A1 because of its high sequence homology to Xenopus cyclin A1, is most highly expressed in germ cells. It has been proposed that cyclin A1 can associate with Cdk2, p39 and Cdc2 p34.
