The heme-based gas sensor, in contrast, is composed of an N-terminal heme-bound gas-sensing domain and a C-terminal functional domain. The association/dissociation of a gaseous molecule to/from the heme-iron complex of a gas sensor triggers the functional domain to regulate various ...
TFRC, essential for the cellular uptake of iron and erythropoiesis,31 and EPO, the principal stimulator of erythropoiesis, are both crucial for healthy RBC genesis and turnover. Remarkably, despite elevated EPO levels, typically indicative of a compensatory response to hypoxia,58 individuals with T21...
[3]. Heme biological functions go beyond those related to the iron atom presence, among these oxygen transport and storage, drug and steroid metabolism, transcriptional and translational regulation are just same examples [4,5]. There is a substantial amount of evidence which indicate heme as ...
Heme (iron protoporphyrin IX) is an essential molecule for numerous living organisms. Not only does it serve as a prosthetic group in enzymes, it also acts as a signaling molecule that controls diverse molecular and cellular processes ranging from signal
