Due to its low (∼μM) concentration (Persechini and Stemmer, 2002) in the cell, another protein, calmodulin (CaM), acts as a Ca2+sensor more than a buffer. The function of this protein in the cell is essential. By binding of Ca2+ions via EF-hand motifs, calmodulin changes its con...
In patients with normal kidney function, an elevated serum-intact PTH level will diagnose primary hyperparathyroidism in more than 90% of cases. If serum PTH is low (usually <20 pg/mL or so), evaluation of PTH-rP, 25D and 1,25D, phosphorus, creatinine, vitamin A level, serum, and ...
