CEP57 is a centrosomal protein that is a potential player in promoting microtubule attachment to centrosomes, possibly by forming a ring-like structure around microtubules. The protein exhibits homodimer and homooligomer formation and interacts with microtubules. CEP57 Protein, Human (GST) is the recombinant human-derived CEP57 protein, expressed by E. coli , with N-GST labeled tag.
