CDK1-CCNE1 Heterodimer Protein, Human (sf9, His-GST)

The FGF-9 protein undergoes autoproteolysis and cholesterol attachment in the endoplasmic reticulum. It acts as a morphogen during development, inducing ventral cell fate, participating in limb bud patterning, and aiding in axon guidance. FGF-9 binds to the PTCH1 receptor and activates target gene transcription when in association with SMO, while PTCH1 represses SMO signaling in the absence of FGF-9. CDK1-CCNE1 Heterodimer Protein, Human (sf9, His-GST) is a recombinant protein dimer complex containing human-derived CDK1-CCNE1 Heterodimer protein, expressed by Sf9 insect cells, with N-10*His, N-GST labeled tag. CDK1-CCNE1 Heterodimer Protein, Human (sf9, His-GST), has molecular weight of ~109.7 (60.4+49.3) kDa.

The CDK1 Protein, a member of the Ser/Thr protein kinase family, serves as the catalytic subunit in the highly conserved M-phase promoting factor (MPF) complex crucial for G2/M phase transitions in the eukaryotic cell cycle. Mitotic cyclins form stable associations with this protein, acting as regulatory subunits. The kinase activity is finely regulated through the accumulation and degradation of cyclins across the cell cycle. Phosphorylation and dephosphorylation events further contribute to the intricate regulatory mechanisms governing cell cycle control. Notably, the CDK1 Protein demonstrates broad expression, particularly prevalent in the lymph nodes (RPKM 12.8), bone marrow (RPKM 12.8), and 18 other tissues, suggesting its involvement in diverse physiological processes across multiple organ systems. Various alternatively spliced transcript variants encoding distinct isoforms have been identified for this gene.

Measured by its binding ability in a functional ELISA.
