产品介绍background:

Lysosomal protective protein/cathepsin A (PPCA) is a lysosomal serine carboxypeptidase that forms an intralysosomal enzyme complex with ?galactosidase and neuraminidase (NEU1). PPCA is synthesized as a 54 kDa precursor/zymogen, and proteolytically cleaved in the lysosome into a catalytically active 32 and 20 kDa two chain enzyme. The enzyme has cathepsin A activity at acidic pH but maintains also a deamidase/esterase activity at neutral pH. Furthermore, the human enzyme, purified from platelets and lymphocytes, has been shown to function on the inactivation of selected neuropeptides, like substance P, oxytocin, and endothelin I. The autosomal recessive genetic deficiency of PPCA causes galactosialidosis, a neurodegenerative lysosomal storage disorder, resulting in the secondary deficiencies of ?galactosidase and NEU1.


Function:

Protective protein appears to be essential for both the activity of beta-galactosidase and neuraminidase, it associates with these enzymes and exerts a protective function necessary for their stability and activity. This protein is also a carboxypeptidase and can deamidate tachykinins.


Subunit:

Heterodimer of a 32 kDa chain and a 20 kDa chain; disulfide-linked.


Subcellular Location:

Lysosome.


DISEASE:

Defects in CTSA are the cause of galactosialidosis (GSL) [MIM:256540]. A lysosomal storage disease associated with a combined deficiency of beta-galactosidase and neuraminidase, secondary to a defect in cathepsin A. All patients have clinical manifestations typical of a lysosomal disorder, such as coarse facies, cherry red spots, vertebral changes, foam cells in the bone marrow, and vacuolated lymphocytes. Three phenotypic subtypes are recognized. The early infantile form is associated with fetal hydrops, edema, ascites, visceromegaly, skeletal dysplasia, and early death. The late infantile type is characterized by hepatosplenomegaly, growth retardation, cardiac involvement, and a normal or mildly affected mental state. The juvenile/form is characterized by myoclonus, ataxia, angiokeratoma, mental retardation, neurologic deterioration, absence of visceromegaly, and long survival.


Similarity:

Belongs to the peptidase S10 family.

Protective protein/Cathepsin A抗体普通抗体重链和轻链的结构

重链结构:普通的**球蛋白具有2条重链(H链),分子量约为50kD,有μ、δ、γ、ε和α五种重链亚型,对应的**球蛋白名称分别为IgMIgGIgAIgDIgE

轻链结构:  普通**球蛋白具有2条轻链(L链),分子质量约25kDa,有κ链和λ链两种亚型,这两种轻链决定了Ig的亚型类别(IgG1IgG2IgG3IgG4)。一个天然的Ig分子两条轻链总是相同的,但在同一个体内可存在分别带有κ或λ链的抗体分子。不同种属生物体内两型轻链的比例不同,正常人血清**球蛋白κ链:λ链约为21,而在小鼠的比例为201

2.2抗体Fab段和Fc

IgG经木瓜蛋白酶酶切后裂解为2个完全相同的Fab段和1Fc,每个Fab段都为单价,可与抗原结合但不会再发生凝集反应;经胃蛋白酶酶切后裂解为1个完整F(ab)2片段和碎片化的Fc片段,F(ab)2片段为双价,可同时结合两个抗原表位。Fab段为抗原结合片段(fragment of antigen bindingFab),相当于抗体分子的两个臂,由一个完整的轻链和重链的VHCH1结构域组成。Fc段为可结晶段(fragment crystallizableFc)相当于IgCH2CH3结构域,是Ig与效应分子或者细胞相互作用的部位。Fab段包含完整的可变区,以及恒定区的CH1区域。Fc段仅指Ig恒定区CH2CH3的区域,相当于Y字结构下面那一部分。
