The CDK6ic complex is an important serine/threonine protein kinase that regulates cell cycle progression and differentiation, promoting the G1/S transition by phosphorylating substrates such as pRB/RB1 and NPM1. It interacts with D-type G1 cyclins during interphase to form active pRB/RB1 kinase, which controls cell cycle entry. CDK6-CCND2 Heterodimer Protein, Human (sf9, GST, FLAG, His) is a recombinant protein dimer complex containing human-derived CDK6-CCND2 Heterodimer protein, expressed by sf9 insect cells , with N-Flag, N-8*His, N-GST labeled tag.
