Cytology
Description

UASt regulates expression of the full-length 2N4R form of Hsap\MAPT in which 14 Ser/Thr sites (Thr111, Thr153, Ser175, Thr181, Ser199, Ser202, Thr205, Thr212, Thr217, Thr231, Ser235, Ser396, Ser404 and Ser422) are changed to alanines mimicking non-phosphorylation, and Asp421 is changed to alanine mimicking non-cleavage at Asp421. Phosphorylation status affects pathogenicity in human patients and the truncated form is associated with Alzheimer's Disease.
