inositol 1,4,5-trisphosphate receptor, type 1; Intracellular channel that mediates calcium release from the endoplasmic reticulum following stimulation by inositol 1,4,5- trisphosphate. Plays a role in ER stress-induced apoptosis. Cytoplasmic calcium released from the ER triggers apoptosis by the activation of CaM kinase II, eventually leading to the activation of downstream apoptosis pathways (By similarity) (2743 aa)

glycoprotein hormones, alpha polypeptide (116 aa)

secretogranin II; Secretogranin-2 is a neuroendocrine secretory granule protein, which is the precursor for biologically active peptides (617 aa)

inositol 1,4,5-trisphosphate receptor, type 2; Receptor for inositol 1,4,5-trisphosphate, a second messenger that mediates the release of intracellular calcium. This release is regulated by cAMP both dependently and independently of PKA (By similarity) (2701 aa)

chromogranin A (parathyroid secretory protein 1); Pancreastatin strongly inhibits glucose induced insulin release from the pancreas (457 aa)

secretogranin III (468 aa)

secretogranin V (7B2 protein); Acts as a molecular chaperone for PCSK2/PC2, preventing its premature activation in the regulated secretory pathway. Binds to inactive PCSK2 in the endoplasmic reticulum and facilitates its transport from there to later compartments of the secretory pathway where it is proteolytically matured and activated. Also required for cleavage of PCSK2 but does not appear to be involved in its folding. Plays a role in regulating pituitary hormone secretion. The C-terminal peptide inhibits PCSK2 in vitro (212 aa)

luteinizing hormone/choriogonadotropin receptor; Receptor for lutropin-choriogonadotropic hormone. The activity of this receptor is mediated by G proteins which activate adenylate cyclase (699 aa)
