I-TASSER model of CCDC57 (yellow) superposed to PDB entry 4jsp chain A (blue), one of the many structure templates associated with phosphoinositide 3-kinase complex. The ligand bound to the 4jsp structure is phosphothiophosphoric acid-adenylate ester (red spheres), which is a small molecule analog of ATP, one of the substrates of phosphoinositide 3-kinases.
