carboxypeptidase E, a prohormone processing exopeptidase and sorting receptor for the regulated secretory pathway, interacts with the dopamine transporter carboxyl terminus and affects dopamine transporter function. Mammalian cell lines coexpressing carboxypeptidase E and dopamine transporter exhibit increased dopamine transporter-mediated dopamine uptake activity compared to cells expressing dopamine transporter alone. Moreover, coexpression of an interfering dopamine transporter-carboxyl terminus minigene inhibit the effects of carboxypeptidase E on dopamine transporter. Functional changes caused by carboxypeptidase E could be attributed to enhanced dopamine transporter expression and subsequent increase in dopamine transporter cell surface localization, due to decreased dopamine transporter degradation. In addition, carboxypeptidase E association could reduce the phosphorylation state of dopamine transporter on serine residues, potentially leading to reduced internalization, thus stabilizing plasmalemmal dopamine transporter localization

physiological function

carboxypeptidase E is classically known as an exopeptidase that cleaves carboxy-terminal basic aminoacids from neuropeptide and peptide hormone intermediates resulting in the production of bioactive peptides inneuroendocrine cells. Carboxypeptidase E that is expressed in the nervous and endocrine systems plays multiple non-enzymatic roles in addition to being an exopeptidase The soluble form of carboxypeptidase E acts as a processing enzyme. The membrane-bound form of carboxypeptidase E serves as a sorting receptor for some proneuropeptides and pro-brain derived neurotrophic factor to target them into the regulated secretory pathway.The cytoplasmic tail of the transmembrane form of carboxypeptidase E is shown to be a key molecule in the anchoring of adrenocorticotropic hormone and brain derived neurotrophic factor vesicles to the microtubule-based transport system for post-Golgi delivery of the vesicles to the release site

physiological function
glutamatergic and acetylcholine synaptic vesicles in the hypothalamus and chromaffin cell-derived PC12 cells employ the transmembrane carboxypeptidase E cytoplasmic tail to interact with gamma-adducin for recruiting synaptic vesicles to the active and/or pre-active zone to facilitate neurotransmitter release. Carboxypeptidase E is a mediator in the process, that mediates localization of synaptic vesicles to the pre-active zone. Carboxypeptidase E has a non-enzymatic role in the control of classical neurotransmitter release in specific neuron
physiological function
-
glutathione S-transferase pull-down and immunoprecipitation analyses indicate that contactin-associated protein 2 is associated with carboxypeptidase E in vitro and in vivo. Both contactin-associated protein 2 and carboxypeptidase E are expressed predominantly in the CNS. Immunohistochemical analysis reveals that both contactin-associated protein 2- and carboxypeptidase E-like immunoreactivities are found to co-localize in the apical dendrites and cell bodies of rat cortical neurons. In subcellular localization analysis, contactin-associated protein 2- and carboxypeptidase E-like immunoreactivities are co-migrated in the fractions of Golgi/ER. The membrane-bound form of carboxypeptidase E functions as a sorting receptor of prohormones in the trans-Golgi network. Carboxypeptidase E may be a key molecule to regulate contactin-associated protein 2 trafficking to the cell membrane

sorting of proglucagon to secretory granules is mediated by carboxypeptidase E
physiological function
overexpression of the secreted form of CPE is accompanied by differential regulation of mRNAs connected to the motility-associated networks, among others adhesion kinase FAK, p21-activated kinase PAK, cell division cycle 42 (Cdc42), integrin, STAT3 as well as TGF-beta. Especially SLUG is downregulated in sCPE-overexpressing glioma cells, paralleled by reduced expression of matrix-metalloproteinases (MMP) and, in consequence, by decreased cell migration. Expression of SLUG is regulated by ERK since inhibition of ERK reverted sCPE-mediated SLUG downregulation and enhanced cell motility. In a mouse glioma model, overexpression of the sectreted form of CPE significantly prolonges survival
physiological function
the enzyme cleaves C-terminal basic amino acids from prohormone intermediates to produce mature peptide hormones and neuropeptides in the endocrine and central nervous systems. It also plays a critical role in prohormone sorting and secretory vesicle transportation. The enzyme exerts multiple non-enzymatic physiological roles in maintaining normal central nervous system function and in neurodevelopment. This includes potent neuroprotective and anti-depressant activities, as well as stem cell differentiation functions. In addition, N-terminal truncated variants of the enzyme regulate expression of important neurodevelopmental genes
