発現特異性:
P42771 CDN2A_HUMAN:

Widely expressed but not detected in brain or skeletal muscle. Isoform 3 is pancreas-specific.

タンパク質の説明:
Acts as a negative regulator of the proliferation of normal cells by interacting strongly with CDK4 and CDK6. This inhibits their ability to interact with cyclins D and to phosphorylate the retinoblastoma protein.

研究背景

機能:

Acts as a negative regulator of the proliferation of normal cells by interacting strongly with CDK4 and CDK6. This inhibits their ability to interact with cyclins D and to phosphorylate the retinoblastoma protein.

PTMs:

Phosphorylation seems to increase interaction with CDK4.

細胞の位置付け:

Cytoplasm. Nucleus.

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
組織特異性:

Widely expressed but not detected in brain or skeletal muscle. Isoform 3 is pancreas-specific.

サブユニット構造:

Heterodimer with CDK4 or CDK6. Predominant p16 complexes contained CDK6. Interacts with CDK4 (both 'T-172'-phosphorylated and non-phosphorylated forms); the interaction inhibits cyclin D-CDK4 kinase activity. Interacts with ISCO2.

タンパク質ファミリー:

Belongs to the CDKN2 cyclin-dependent kinase inhibitor family.
