Kallikrein-3/PSA 蛋白, Human (237a.a, HEK293, His)

Kallikrein-3 (PSA) protein, pivotal in the male reproductive system, hydrolyzes semenogelin-1, a seminal vesicle protein. This enzymatic activity initiates seminal coagulum liquefaction, crucial for sperm mobility and fertility. PSA's cleavage of semenogelin-1 highlights its importance in the complex processes of semen physiology and male reproductive function. Kallikrein-3/PSA Protein, Human (237a.a, HEK293, His) is the recombinant human-derived Kallikrein-3/PSA protein, expressed by HEK293 , with C-6*His labeled tag. The total length of Kallikrein-3/PSA Protein, Human (237a.a, HEK293, His) is 237 a.a., with molecular weight of ~35.0 kDa.

激肽释放酶-3 (PSA) 蛋白通过水解精囊蛋白 Semenogelin-1，在男性生殖系统中发挥关键作用。这种酶活性负责启动精浆的液化，这是精子活动性和整体生育力的关键步骤。PSA 裂解 Semenogelin-1 的能力强调了其在涉及精液生理学和男性生殖功能的复杂过程中的重要性。

The enzyme activity of this recombinant protein is testing in progress, we cannot offer a guarantee yet.
