physiological function
physiological function
aspartyl aminopeptidase is a moonlight protein that has aspartyl aminopeptidase and chaperone activities
physiological function
-
a small portion localizes in the vacuole, but its vacuolar transport is accelerated by nutrient starvation, and it stably resides in the vacuole lumen, it is proposed that cytosolic enzyme is redistributed to the vacuole when yeast cells need more active vacuolar degradation
physiological function
-
aspartyl aminopeptidase interacts with ClC-5, a chloride/proton exchanger that plays an obligate role in albumin uptake by the renal proximal tubule. ClC-5 forms an endocytic complex with the albumin receptor megalin/cubilin. Aspartyl aminopeptidase and ClC-5 associate in cells. The two proteins bind directly to each other. Overexpression of wild-type aspartyl aminopeptidase increases cell-surface levels of ClC-5 and albumin uptake. Overexpression results in significant decrease in the amount of G actin, suggesting a role for aspartyl aminopeptidase in stabilizing the cytoskeleton
physiological function
-
aspartyl aminopeptidase immunoprecipitates with beta-actin and tubulin, suggesting a role in cytoskeletal maintenance. Enzyme is not present in the urine of healthy rats, however, it is readily detected in the urine in rat models of mild and heavy proteinuria. Urinary levels correlate with the severity of proteinuria

in complex with zinc and substrate analogue aspartate-beta-hydroxamate, to 2.2 A resolution. Structure reveals a dodecameric machinery built by domain-swapped dimers, in agreement with electron microscopy data. For both Asp-Ala and Glu-Ala substrates, the Asp and Glu side chains fit into the P1 substrate pocket without steric constraints, while the main chain is modeled onto the hydroxamate group of aspartate-beta-hydroxamate in a position optimal for hydrolysis. The P1 substrate pocket is created by strand beta15 and the beta16-alpha12 and beta17-alpha13 loops, with the beta17-lpha13 loop lining the wall and restricting the dimensions of the pocket. This limited space disfavours bulky hydrophobic residues
