Function May be involved in the proteolytic inactivation of enkephalins and neurotensin in some brain areas. May convert inactive angiotensin I into the biologically active angiotensin II. {ECO:0000269PubMed:18178555}.
Subcellular Localization Secreted, extracellular space, extracellular matrix {ECO:0000269PubMed:18178555}.
Disease Associations Note=A chromosomal aberration involving CPA6 was found in a patient with Duane retraction syndrome. Translocation t(6;8)(q26;q13).Epilepsy, familial temporal lobe, 5 (ETL5) [MIM:614417]: A focal form of epilepsy characterized by recurrent seizures that arise from foci within the temporal lobe. Seizures are usually accompanied by sensory symptoms, most often auditory in nature. {ECO:0000269PubMed:21922598}. Note=The disease is caused by mutations affecting the gene represented in this entry.Febrile seizures, familial, 11 (FEB11) [MIM:614418]: Seizures associated with febrile episodes in childhood without any evidence of intracranial infection or defined pathologic or traumatic cause. It is a common condition, affecting 2-5% of children aged 3 months to 5 years. The majority are simple febrile seizures (generally defined as generalized onset, single seizures with a duration of less than 30 minutes). Complex febrile seizures are characterized by focal onset, duration greater than 30 minutes, and/or more than one seizure in a 24 hour period. The likelihood of developing epilepsy following simple febrile seizures is low. Complex febrile seizures are associated with a moderately increased incidence of epilepsy. {ECO:0000269PubMed:21922598}. Note=The disease is caused by mutations affecting the gene represented in this entry.
Tissue Specificity Expressed in the hippocampus, nucleus raphe, and cortex. {ECO:0000269PubMed:21922598}.
