Function
Regulatory subunit of tax-6/calcineurin A, a calcium-dependent, calmodulin-stimulated protein phosphatase (PubMed:12221132). Confers calcium sensitivity (PubMed:12221132). Plays a role in egg-laying, fertility, growth, movement and cuticle development (PubMed:12221132, PubMed:12684004). Plays a role in sensitivity to CO2 levels (PubMed:18524955). Regulates expression of tax-6 inhibitor rcn-1 (PubMed:12684004). Negatively regulates nicotinic acetylcholine receptor (nAChR) sensitivity to nicotine (PubMed:15990870). Negatively regulates lifespan (PubMed:19279398). Involved in endocytic processes including coelomocyte endocytosis, intestine apical endocytosis and synaptic vesicle recycling (PubMed:20803083, PubMed:21345307). May negatively regulate autophagy (PubMed:19279398).
