Renin is known as a secretory glycoprotein produced, stored and released by the kidney. Renin cleaves angiotensin (ANG) I from angiotensinogen, which is further cleaved to ANG II by ANG-converting enzyme. ANG II acts via specific receptors located at the cell membrane. Recently renin transcripts have been discovered which encode ...

Alternative splicing is an important mechanism for modulating gene function that accounts for a considerable proportion of proteomic complexity in higher eukaryotes. Alternative splicing is often tightly regulated in a cell-type- or developmental-stage- specific manner and can cause a single gene to have multiple functions. Human Tissue transglutaminase (TGM2) is ...
