Title: The Biochemistry and Physiology of Peptidases
Description: Peptidases regulate important physiological processes by controlling levels of bioactive peptides and occasionally through noncatalytic processes. This thesis presents a study of prolyl endopeptidase-like (PREPL), which is a peptidase involved in several human deletion syndromes, including hypotonia-cystinuria syndrome (HCS). Phenotypes tentatively attributed to PREPL deletion include hypotonia and decreased growth hormone (GH) levels. However, little is known about the mechanisms by which PREPL deletion causes these phenotypes.
