기능 설명

Vimentins are class-III intermediate filaments found in various non-epithelial cells, especially mesenchymal cells. Vimentin is attached to the nucleus, endoplasmic reticulum, and mitochondria, either laterally or terminally. Plays a role in cell directional movement, orientation, cell sheet organization and Golgi complex polarization at the cell migration front (By similarity). Protects SCRIB from proteasomal degradation and facilitates its localization to intermediate filaments in a cell contact-mediated manner (By similarity). May promote axon outgrowth and motor fiber repair via DSP-mediated recruitment to outgrowth tips (By similarity) Involved with LARP6 in the stabilization of type I collagen mRNAs for CO1A1 and CO1A2

波形蛋白是在各种非上皮细胞，尤其是间充质细胞中发现的 III 类中间丝。波形蛋白附着在细胞核、内质网和线粒体的侧面或末端。在细胞迁移前沿的细胞定向运动、方向、细胞片组织和高尔基复合体极化中发挥作用（通过相似性）。保护 SCRIB 免受蛋白酶体降解，并促进其以细胞接触介导的方式定位到中间丝（通过相似性）。可以通过 DSP 介导的募集到生长尖端来促进轴突生长和运动纤维修复（通过相似性）参与 LARP6 稳定 CO1A1 和 CO1A2 的 I 型胶原蛋白 mRNA

•Filament disassembly during mitosis is promoted by phosphorylation at Ser-55 as well as by nestin (By similarity). One of the most prominent phosphoproteins in various cells of mesenchymal origin. Phosphorylation is enhanced during cell division, at which time vimentin filaments are significantly reorganized. Phosphorylation by PKN1 inhibits the formation of filaments. Phosphorylated at Ser-56 by CDK5 during neutrophil secretion in the cytoplasm (PubMed:21465480). Phosphorylated by STK33 (PubMed:18811945). Phosphorylated on tyrosine residues by SRMS (PubMed:29496907)
•O-glycosylated during cytokinesis at sites identical or close to phosphorylation sites, this interferes with the phosphorylation status
•S-nitrosylation is induced by interferon-gamma and oxidatively-modified low-densitity lipoprotein (LDL(ox)) possibly implicating the iNOS-S100A8/9 transnitrosylase complex
