G-protein-signaling modulator 2 (GPSM2)

Plays an important role in mitotic spindle pole organization via its interaction with NUMA1 (PubMed:11781568, PubMed:15632202, PubMed:21816348). Required for cortical dynein- dynactin complex recruitment during metaphase (PubMed:22327364).

Plays a role in metaphase spindle orientation (PubMed:22327364). Plays also an important role in asymmetric cell divisions (PubMed:21816348).
