SPICE1

Chr 3

spindle and centriole associated protein 1

Also known as: CCDC52, SPICE

Involved in metaphase chromosome alignment; mitotic spindle assembly; and regulation of centriole replication. Located in intracellular membrane-bounded organelle; microtubule cytoskeleton; and plasma membrane. [provided by Alliance of Genome Resources, Apr 2025]
