產(chǎn)品介紹 Pigment epithelium derived factor, originally identified in conditioned medium of cultured human fetal retinal pigment epithelial (RPE) cells, is a neurotrophic protein that induces extensive neuronal differentiation in human Y79 retinoblastoma cells, a neoplastic counterpart of normal retinoblasts. It has been suggested that PEDF is synthesized by RPE cells and secreted into the retina interphotoreceptor matrix where it may influence development/differentiation of the neural retina. PEDF is a potent inhibitor of angiogenesis. As it does not undergo the S (stressed) to R (relaxed) conformational transition characteristic of active serpins, it exhibits no serine protease inhibitory activity. The PEDF gene is a member of the serpin gene family. Serpins are a group of serine protease inhibitors, some of which have also been reported to exhibit neurotrophic activity.

Function : Neurotrophic protein; induces extensive neuronal differentiation in retinoblastoma cells. Potent inhibitor of angiogenesis. As it does not undergo the S (stressed) to R (relaxed) conformational transition characteristic of active serpins, it exhibits no serine protease inhibitory activity.

Subcellular Location : Secreted. Melanosome. Enriched in stage I melanosomes.

Tissue Specificity : Retinal pigment epithelial cells and blood plasma.

N- and O-glycosylated. O-glycosylated with a core 1 or possibly core 8 glycan.

DISEASE : Defects in SERPINF1 are the cause of osteogenesis imperfecta type 12 (OI12) [MIM:613982]. OI12 is a connective tissue disorder characterized by bone fragility, low bone mass, and recurrent fractures. OI12 is characterized by features compatible with osteogenesis imperfecta type III in the Sillence classification. Patients have normal grayish sclerae and fractures of long bones and severe vertebral compression fractures, with resulting deformities observed as early as the first year of life.

Similarity : Belongs to the serpin family.

色素上皮衍生因子（PEDF）是人及動物眼中天然存在的一種糖蛋白，屬于絲氨酸蛋白酶抑制劑家族，目前研究認為：它具有新生和神經(jīng)營養(yǎng)功能的雙重作用。

過去曾對PEDF的神經(jīng)保護作用及研究較多，在很多組織中都有不同的表達。

目前研究認為；PEDF是最為有效的眼內(nèi)新生天然抑制劑，對新生的形成起著重要的調(diào)控作用。
