Rabbit Anti-PCM1 (Pericentriolar Material 1, PTC4)

The PCM1 protein was originally identified by virtue of its distinct cell cycle-dependent association with the centrosome complex and microtubules. The protein appears to associate with the centrosome complex during the cell cycle. Dissociation occurs during mitosis when PCM1 is dispersed throughout the cell. Immunolabeling studies performed found that PCM1 was present in centriolar satellites and in electron dense granules between 70 and 100 nm in diameter. These were originally thought to be scattered only around the centrosomes, but further studies proved that PCM1 was also found throughout the cytoplasm.PCM1 forms a complex at the centrosome with DISC1 and BBS4, which provides a link between aberrant PCM1 and the abnormal cortical development associated with the pathology of schizophrenia.
