Background: Calcineurin, also known as protein phosphatase 2B (PP2B), is a calmodulin-dependent, calcium-activated, serine/threonine protein phosphatase composed of a catalytic subunit (calcineurin A) and a tightly bound regulatory subunit (calcineurin B) (1). Calcineurin A is highly homologous to protein phosphatases 1 and 2A. Calcineurin B, like calmodulin, contains four EF-hand, calcium-binding motifs.Calcineurin signaling has been implicated in a broad spectrum of cellular processes including cell-cycle regulation, stress response and apoptosis and is required for proper cardiovascular and skeletal muscle development (2,3). Calcineurin-mediated dephosphorylation of the nuclear factor of activated T cells (NFAT) transcription factor is essential for NFAT activation and nuclear translocation and early gene expression in T lymphocytes (2,3). Calcineurin is the target of the immunosuppressive drugs Cyclosporin A and FK506, both of which block the activation of quiescent T cells after T cell receptor engagement (2,3). Cyclosporin A and FK506 bind to the immunophilins, cyclophilin and FKBP respectively and the immunophilin-drug complex binds to calcineurin and blocks substrate binding.

Background: Myosin Va is a molecular motor protein involved in the transport of organelles, vesicles and other cellular cargo along actin filaments (reviewed in 1). The molecule consists of two identical heavy chains, which dimerize via helical domains in a coiled coil structure. The amino-terminal motor domains of the heavy chains contain both the ATPase and the actin-binding activities of myosin Va. The globular tail domains act in a regulatory capacity, binding the myosin Va cargo (2) or inhibiting motor activity by binding the head domains and preventing ATP consumption (3). Mutation of the murine dilute gene, which encodes myosin Va, causes defects in coat pigmentation as well as severe neurological defects (4). In melanocytes, the coiled coil structure of myosin Va is important in regulating the trafficking of melanosomes in conjunction with melanophilin and Rab27a (5). Myosin Va regulates trafficking and exocytosis of secretory granules in neuroendocrine cells (reviewed in 6) as well as RNA transport and distribution (7).

Background: GPR37 is a G protein-coupled receptor (GPCR) that was originally identified as an orphan receptor highly expressed in the brain and testis (1). It shares significant homology with the receptors of endothelin and bombesin peptides (1). Neuropeptide head activator from the invertebrate Hydra was identified as a high-affinity ligand of GPR37 (2), however, to date, no mammalian ortholog of this peptide that could represent an endogenous GPR37 ligand has been identified. Recently, GPR37 was deorphanized as the receptor for the endogenous peptides prosaptide and prosaposin (3). GPR37 is a substrate of the E3 ubiquitin ligase parkin, and is often referred to as “parkin-associated endothelin-like receptor,” or “Pael-R” (4). GPR37 has been implicated in the pathogenesis of Parkinson’s Disease as it aggregates in the substantia nigra of some PD patients (4,5). Interestingly, prosaposin exerts neuroprotective, neurotrophic, and gliotrophic actions (6), and GPR37 was identified as a negative regulator of oligodendrocyte differentiation and myelination (7), suggesting that it could represent a potential target for demyelinating pathologies.
