The function of Ensembl gene identifier ENSG00000152332 (UHMK1, U2AF homology motif kinase 1) is as follows. Upon serum stimulation, phosphorylates CDKN1B/p27Kip1, thus controlling CDKN1B subcellular location and cell cycle progression in G1 phase. May be involved in trafficking and/or processing of RNA (By similarity). .
