脂滴包被蛋白Perilipin-A抗体的功能抗体的主要功能是与抗原（包括外来的和自身的）相结合，从而有效地清除侵入机体内的微生物、寄生虫等异物，抗体（antibody）是一种应答抗原产生的、可与抗原特异性结合的蛋白质。每种抗体与特定的抗原决定基结合。这种结合可以使抗原失活，也可能无效但有时也会对机体造成病理性损害，如抗核抗体、抗双链DNA抗体、抗甲状腺球蛋白抗体等一些自身抗体的产生，对人体可造成危害。

产品介绍 Perilipins, members of the PAT protein family (named after lipid droplet proteins Perilipin, Adipophilin, and TIP47) are found exclusively at the surface of lipid droplets in adipocytes and steroidogenic cells. They have been suggested to function as regulators of lipolysis and triacylglycerol storage within adipose tissue. Four distinct isoforms ranging from perilipin A (57 kDa) to perilipin D (26 kDa) have been identified and they share an identical amino terminal sequences, and contain 2–6 consensus protein kinase A (PKA) phosphorylation sites. Perilipin C and D have been detected only in steroidogenic cells. Perilipin A is the most abundant form on the lipid droplets of adipocytes. The phosphorylation of perilipin by PKA, which is accompanied by the phosphorylation and translocation of hormone-sensitive lipase from the cytosol to the lipid droplets, promotes lipolysis. There is evidence for the presence of perilipin A in atheroma plaques suggesting that the protein may be involved in the development of therosclerosis by controlling as in adipocytes the hydrolysis of stored lipids.

Function : Modulator of adipocyte lipid metabolism. Coats lipid storage droplets to protect them from breakdown by hormone-sensitive lipase (HSL). Its absence may result in leanness.

Subunit : Interacts with ABHD5.

Subcellular Location : Lipid droplet. Note=Lipid droplet surface-associated.

Tissue Specificity : Adipocytes.

Post-translational modifications : Major cAMP-dependent protein kinase-substrate in adipocytes, also dephosphorylated by PP1. When phosphorylated, may be maximally sensitive to HSL and when unphosphorylated, may play a role in the inhibition of lipolysis, by acting as a barrier in lipid droplet.

DISEASE : Defects in PLIN1 are the cause of familial partial lipodystrophy type 4 (FPLD4) [MIM:613877]. FPLD4 is a form of lipodystrophy characterized by loss of subcutaneous adipose tissue primarily affecting the lower limbs, insulin-resistant diabetes mellitus, hypertriglyceridemia, and hypertension.

Similarity : Belongs to the perilipin family.

    脂肪细胞中贮存的甘油三酯的水解是人和动物体内精细调节的动态平衡过程，与维持机体能量的动态平衡和代谢正常密切相关。Perilipin A是成熟脂肪细胞中脂滴膜上表达量较多的一种结构和功能蛋白，是多条脂解通路的终末靶点之一，对脂肪细胞的脂肪分解起着关键的调控作用.

    perilipin可能在脂肪分解调控中起到“分子开关”的作用。蛋白激酶A（PKA）、细胞外信号调节激酶（ERK）等信号转导通路参与了脂肪分解。肿瘤坏死因子仅（TNFα）、过氧化物酶体增殖物激活受体γ（PPAγ）激动剂、瘦素（leptin）均可以影响perilipin的表达。近年来研究，perilipin可通过蛋白酶体途径来调节其蛋白量的表达。脂肪分解调控中的关键蛋白perilipin对2型糖尿病、肥胖、动脉粥样硬化等多种代谢性疾病及心血管疾病相关联。
