Leucine-rich repeat and guanylate kinase domain-containing protein; Involved in multiple aspects of sperm assembly including acrosome attachment, shaping of the sperm head and in the early aspects of axoneme development. Not essential for primary cilium biogenesis.

Cilia- and flagella-associated protein 74; As part of the central apparatus of the cilium axoneme may play a role in cilium movement.

Sperm-associated antigen 17; Component of the central pair apparatus of ciliary axonemes. Plays a critical role in the function and structure of motile cilia. May play a role in endochondral bone formation, most likely because of a function in primary cilia of chondrocytes and osteoblasts.

Sperm-associated antigen 6; Important for structural integrity of the central apparatus in the sperm tail and for flagellar motility.

Calmodulin-like protein 6; Calmodulin like 6; Belongs to the calmodulin family. Calglandulin subfamily.

Calmodulin-like protein 3; May function as a specific light chain of unconventional myosin-10 (MYO10), also enhances MYO10 translation, possibly by acting as a chaperone for the emerging MYO10 heavy chain protein. May compete with calmodulin by binding, with different affinities, to cellular substrates.

Calmodulin-like protein 5; Binds calcium. May be involved in terminal differentiation of keratinocytes.

Calmodulin-like protein 4; Calmodulin like 4; Belongs to the calmodulin family.

Calmodulin-1; Calmodulin mediates the control of a large number of enzymes, ion channels, aquaporins and other proteins through calcium-binding. Among the enzymes to be stimulated by the calmodulin-calcium complex are a number of protein kinases and phosphatases. Together with CCP110 and centrin, is involved in a genetic pathway that regulates the centrosome cycle and progression through cytokinesis. Mediates calcium-dependent inactivation of CACNA1C. Positively regulates calcium-activated potassium channel activity of KCNN2.
