Highly expressed in testis and placenta. Low levels in bronchial epithelial cells.

描述:
CCNE1 a member of the highly conserved cyclin family, whose members are characterized by a dramatic periodicity in protein abundance through the cell cycle. Cyclins function as regulators of CDK kinases. Forms a complex with and functions as a regulatory subunit of CDK2, whose activity is required for cell cycle G1/S transition. Accumulates at the G1-S phase boundary and is degraded as cells progress through S phase. Two alternatively spliced isoforms have been described.

研究背景

功能:

Essential for the control of the cell cycle at the G1/S (start) transition.

翻译修饰:

Phosphorylation of both Thr-395 by GSK3 and Ser-399 by CDK2 creates a high affinity degron recognized by FBXW7, and accelerates degradation via the ubiquitin proteasome pathway. Phosphorylation at Thr-77 creates a low affinity degron also recognized by FBXW7.

Ubiquitinated by UHRF2; appears to occur independently of phosphorylation.

细胞定位:

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
组织特异性:

Highly expressed in testis and placenta. Low levels in bronchial epithelial cells.

亚基结构:

Interacts with CDK2 protein kinase to form a serine/threonine kinase holoenzyme complex. The cyclin subunit imparts substrate specificity to the complex. Found in a complex with CDK2, CABLES1 and CCNA1 (By similarity). Part of a complex consisting of UHRF2, CDK2 and CCNE1. Interacts directly with UHRF2; the interaction ubiquitinates CCNE1 and appears to occur independently of CCNE1 phosphorylation. Interacts with INCA1.

蛋白家族:

Belongs to the cyclin family. Cyclin E subfamily.
