|Application ||WB, IF|
|Calculated MW||32520 Da|
|Other Names||G1/S-specific cyclin-D3, CCND3|
|Target/Specificity||A synthetic peptide corresponding to a residue near the C-term of human Cyclin D3 was used as an immunogen.|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||Cyclin D3 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Regulatory component of the cyclin D3-CDK4 (DC) complex that phosphorylates and inhibits members of the retinoblastoma (RB) protein family including RB1 and regulates the cell-cycle during G(1)/S transition. Phosphorylation of RB1 allows dissociation of the transcription factor E2F from the RB/E2F complex and the subsequent transcription of E2F target genes which are responsible for the progression through the G(1) phase. Hypophosphorylates RB1 in early G(1) phase. Cyclin D-CDK4 complexes are major integrators of various mitogenenic and antimitogenic signals. Also substrate for SMAD3, phosphorylating SMAD3 in a cell-cycle-dependent manner and repressing its transcriptional activity. Component of the ternary complex, cyclin D3/CDK4/CDKN1B, required for nuclear translocation and activity of the cyclin D-CDK4 complex.|
|Cellular Location||Nucleus. Cytoplasm. Membrane. Note=Cyclin D-CDK4 complexes accumulate at the nuclear membrane and are then translocated to the nucleus through interaction with KIP/CIP family members|

Cyclin D3 is a member of Cyclin D family which mediates cell cycle progression through the G1 phase. Cyclin D family binds and activates cyclin-dependent kinases 4 and 6 (CDK4, CDK6), which regulates the phosphorylation of retinoblastoma (Rb) protein, p107, and p130 (1). Cyclin D3, similar to cyclin D1 and D2, regulates the initial G1 to S transition by inhibiting Rb and activating E2F proteins (2). Cyclin D3 expression has been linked to inhibition of granulocyte differentiation and activation of various transcription factors, such as transcription factor 5 (3, 4). Overexpression of cyclin D3 is associated with poor clinical outcome in diffuse large B-cell lymphoma cases (5).
