Proceedings of the National Academy of Sciences of the United States of America, Vol. 74, No. 8 (Aug., 1977), pp. 3404-3408 (5 pages) The increase in human leukocyte adenosine 3′:5′-cyclic ...
cyclic AMP and cyclic GMP are universal second messengers and are sensed by receptor proteins that contain cyclic nucleotide binding (CNB) domains. In mammal, CNB domains are found in protein kinase A ...
Cyclic adenosine monophosphate (cAMP) is a ubiquitous second messenger that underpins a wide array of physiological processes. It activates multiple effector pathways, most notably protein kinase A ...
A membranal proteinase from brush-border epithelial cells of the rat small intestine was shown to bring about a restricted and limited degradation of the free catalytic subunit (C) of cyclic ...
Infertility affects about one in six couples, and male factors account for roughly half of all cases—often because sperm ...
The protein complex (TMEM217-SLC9C1) is a key for the function of a special enzyme (sAC) in the mature sperm, which improves the motility to achieve fertilization.
