Centrosome & spindle pole-associated protein 1 (CSPP1, CSSP)

Function

• may play a role in cell-cycle-dependent microtubule organization
• phosphoryated
• phosphorylation increases in colcemide-treated cells

Compartment

• centrosome
• associated with mitotic spindles

Alternative splicing

named isoforms=2

Expression

• detected in testis
• expression of isoform 1 increases throughout the cell cycle & peaks in G2/M phase
• expression of isoform 2 is highest in G1 phase & decreases thereafter

More general terms

• cytoskeletal protein
• phosphoprotein
