Speract TFA(76901-59-2(free base)) 是一种海胆卵肽，可调节精子活力，也可刺激精子线粒体代谢。

Speract TFA is a sea urchin egg peptide that regulates sperm motility, also stimulates sperm mitochondrial metabolism.

The stimulation of sperm with speract depolarizes the mitochondrion and increases the levels of NADH.?Surprisingly, these responses are independent of external Ca(2+) and are due to the increase in intracellular pH (pHi) induced by speract.?Speract, by regulating pHi, in addition to [Ca(2+)]i, may finely modulate mitochondrial metabolism to control motility and ensure that sperm reach the egg and fertilize it[1].
