植物磺肽素PSK/179667-62-0/Phytosulfokine

Product Name：Phytosulfokine

CAS No.：179667-62-0

Synonyms：植物磺肽素PSK

Catalog No.：220P454

Brand：Typeptide Biotech（肽研生物）

Description：Phytosulfokine是由5个氨基酸构成的磺化短肽，其中2个酪氨酸残基被磺酸化修饰1。磺酸化修饰增加了肽的极性和水溶性，同时可能影响其与受体的结合能力。氨基酸通过肽键连接成线性结构，整体相对较短小，空间结构较为紧凑。Phytosulfokine通过与细胞膜上的富含亮氨酸的类受体激酶（LRR-RLK）蛋白家族作为受体结合，向胞内传递信号。拟南芥中报道的 PSK 受体 PSKR 具有激酶活性和鸟苷酸环化酶活性双重信号感知作用，可激活下游一系列信号通路，从而调控植物多种生理和生化反应。研究表明，PSK 可调控植物细胞的体外分化、细胞的生长、根顶端分生组织细胞和静止中心细胞的调控、花粉管细胞的发育等。同时，其参与非生物胁迫应答，以及和生长素、细胞分裂素、茉莉酸、油菜素内酯等植物激素的协同调控等，在植物生长、发育和逆境应答中发挥重要作用。

Phytosulfokine is a sulfonated short peptide composed of 5 amino acids, with 2 tyrosine residues modified by sulfonation. Sulfonation modification increases the polarity and water solubility of peptides, while potentially affecting their binding ability to receptors. Amino acids are connected by peptide bonds to form a linear structure, which is relatively short and compact in spatial structure. Phytosulfokine binds to the leucine rich receptor like kinase (LRR-RLK) protein family on the cell membrane as receptors, transmitting signals into the cell. The PSK receptor PSKR reported in Arabidopsis has dual signal sensing effects of kinase activity and guanylate cyclase activity, which can activate a series of downstream signaling pathways and regulate various physiological and biochemical reactions in plants. Research has shown that PSK can regulate in vitro differentiation of plant cells, cell growth, regulation of root apical meristematic cells and quiescent center cells, and development of pollen tube cells. At the same time, it participates in the response to abiotic stress and plays an important role in the coordinated regulation of plant hormones such as auxin, cytokinin, jasmonic acid, brassinolide, etc., in plant growth, development, and stress response.
