OrganismHomo sapiens

Kla Sites from experimental identification

Position Flanking peptide
38 EKYSSLQKTPVWKGR
43 LQKTPVWKGRNTSSA

Function

Acts as a tumor suppressor. Inhibits DNA synthesis. Its ability to inhibit oncogenic transformation is mediated through its association with RB1. Plays a role in the expression of genes required for the G1/S transition
