kaptin (actin-associated protein 2E4, KPTN)

Function

• may be involved in actin dynamics
• may play a role in producing the sensory apparatus in hair cells
• may play a role in actin rearrangements that accompany platelet activation & stereocilia formation
• associates with one end of F-actin filaments

Compartment

• cytoplasm, perinuclear region, cell projection, stereocilium, growth cone
• perinuclear at the tips of stereocilium in the inner ear
• localized at sites of actin polymerization in motile f fibroblasts & neuronal growth cones

More general terms

• cytoskeletal protein
