Calmodulin Interacts and Regulates Enzyme Activity of the Mammalian Sperm Phospholipase C
( Elsevier , 2017 , Article)Sperm-specific Phospholipase C zeta (PLCζ) is widely considered to be the sole, physiological stimulus responsible for the generation of Ca2+ oscillations that induce egg activation and early embryo development during ... -
Calmodulin Mutations Associated with Congenital Cardiac Disease Display Novel Biophysical and Biochemical Characteristics
( Elsevier , 2018 , Article)Calmodulin (CaM) is a cytoplasmic multifunctional calcium (Ca2+)-binding messenger that interacts with the cardiac ryanodine receptor (RyR2), a large transmembrane Ca2+ channel that mediates Ca2+ release from the sarcoplasmic ... -
Caloric expenditure estimation for health games
( Hamad bin Khalifa University Press (HBKU Press) , 2013 , Conference Paper)With the decline in physical activities among young people, it is essential to monitor their physical activity and ensure their calorie expenditure is within the range necessary to lead a healthy life style. For many ... -
