PPARD基因编码的功能和结构描述

该基因编码过氧化物酶体增殖物激活受体（PPAR）家族的成员。编码的蛋白质被认为是转录抑制和核受体信号传导的一个整合体。它可能会抑制配体诱导的过氧化物酶体增殖物激活受体α和γ的转录活性，尽管这种效应的证据是不一致的。这种基因在结直肠癌细胞中的表达可能是可变的，但通常相对较低。小鼠的基因敲除研究表明该蛋白在胼胝体髓鞘形成、脂质代谢、分化和表皮细胞增殖中起作用。选择性剪接导致编码不同蛋白质亚型的多个转录变体。

This gene encodes a member of the peroxisome proliferator-activated receptor (PPAR) family. The encoded protein is thought to function as an integrator of transcriptional repression and nuclear receptor signaling. It may inhibit the ligand-induced transcriptional activity of peroxisome proliferator activated receptors alpha and gamma, though evidence for this effect is inconsistent. Expression of this gene in colorectal cancer cells may be variable but is typically relatively low. Knockout studies in mice suggested a role for this protein in myelination of the corpus callosum, lipid metabolism, differentiation, and epidermal cell proliferation. Alternative splicing results in multiple transcript variants encoding distinct protein isoforms.
