WebCystatin C is 13,000-D cysteine proteinase inhibitor produced by all nucleated cells at a constant rate. It is freely filtered at the glomerulus, and then, it undergoes catabolism within the kidney tubules, resulting in no urinary excretion. Thus, the serum level of cystatin C depends on GFR, and it can be used as a measure of kidney function ... WebJan 1, 2005 · Cystatin C (cys-C) is a low molecular mass protein that was initially known as inter alia γ-trace, post-γ-globulin, and gamma-CSF. The amino acid sequence of the single polypeptide chain of human cys-C was determined in 1981 [1]. The protein did not display any significant homology with the sequences of any protein at that time. brz on a track dayWebApr 13, 2024 · Cystatin C-based GFR equations typically give an estimation of kidney function that is independent of muscle mass and diet [55, 56].
