背景介紹：Phosphorylated derivatives of phosphatidylinositol (PtdIns) regulate cytoskeletal functions, membrane trafficking, and receptor signaling by recruiting protein complexes to cell- and endosomal-membranes. Humans have multiple PtdIns proteins that differ by the degree and position of phosphorylation of the inositol ring. This gene encodes an enzyme (PIKfyve; also known as phosphatidylinositol-3-phosphate 5-kinase type III or PIPKIII) that phosphorylates the D-5 position in PtdIns and phosphatidylinositol-3-phosphate (PtdIns3P) to make PtdIns5P and PtdIns(3,5)biphosphate. The D-5 position also can be phosphorylated by type I PtdIns4P-5-kinases (PIP5Ks) that are encoded by distinct genes and preferentially phosphorylate D-4 phosphorylated PtdIns. In contrast, PIKfyve preferentially phosphorylates D-3 phosphorylated PtdIns. In addition to being a lipid kinase, PIKfyve also has protein kinase activity. PIKfyve regulates endomembrane homeostasis and plays a role in the biogenesis of endosome carrier vesicles from early endosomes. Mutations in this gene cause corneal fleck dystrophy (CFD); an autosomal dominant disorder characterized by numerous small white flecks present in all layers of the corneal stroma. Histologically, these flecks appear to be keratocytes distended with lipid and mucopolysaccharide filled intracytoplasmic vacuoles. Alternative splicing results in multiple transcript variants encoding distinct isoforms.

磷脂酰肌醇3磷酸激酶5Ⅲ型抗體,PIP5K3抗體產品信息：

初次體液免疫是指宿主*次接觸外來TD抗原后血清中逐漸出現抗原特異性抗體的過程。初次體液免疫應答的延遲相（從抗原免疫到抗體水平達到高峰的時間）為6-10天，起初幾天血清中的抗原特異性抗體主要為親和力較低的IgM,后期以IgG為主。初次應答過程的血清中抗原特異性抗體的高峰濃度較低且維持時間較短。再次體液免疫應答是指曾被某抗原免疫過的宿主再次接觸該抗原時血清中迅速出現抗原特異性抗體的過程，其延遲相僅為4-5天，血清抗體以IgG為主，其高峰濃度較高且維持時間較長。再次應答所產生的抗體還有親和力成熟現象，即該抗體與抗原的親和力明顯高于初次應答產生的抗體。

免疫應答過程：

1.抗原進入機體；

2.抗原刺激 B淋巴細胞，使之分化增殖成為抗體分泌漿細胞和記憶細胞（初次免疫應答）；

3.抗體主要由漿細胞分泌 ；

4.記憶細胞再次受到特異性抗原刺激后會被激活而成為分泌抗體的漿細胞（再次免疫應答）；

5.記憶B細胞是長命細胞，可以存活數月甚至機體終生
