Disease

CDC5L_HUMAN Note=A chromosomal aberration involving CDC5L is found in multicystic renal dysplasia. Translocation t(6;19)(p21;q13.1) with USF2.

Function

CDC5L_HUMAN DNA-binding protein involved in cell cycle control. May act as a transcription activator. Component of the PRP19-CDC5L complex that forms an integral part of the spliceosome and is required for activating pre-mRNA splicing.[1] [2] [3] [4] [5] [6] [7] [8] [9]
