摘要

Phafin2是一种外周蛋白，可触发内体和溶酶体间室的细胞信号。Phafin2的特异性亚细胞定位是通过一系列磷脂酰肌醇3-磷酸(PtdIns3P)结合域、pleckstrin同源性(PH)和Fab-1、YOTB、Vac1和EEA1 (FYVE)结构域的存在介导的。绑定到PtdIns3P的两个域的需求仍然不清楚。为了详细了解Phafin2 PH结构域的分子相互作用，我们报告了其几乎完整的1H, 15N和13C骨干共振分配。

Backbone 1H, 15N, and 13C resonance assignments of the Phafin2 pleckstrin homology domain

Phafin2 is a peripheral protein that triggers cellular signaling from endosomal and lysosomal compartments. The specific subcellular localization of Phafin2 is mediated by the presence of a tandem of phosphatidylinositol 3-phosphate (PtdIns3P)-binding domains, the pleckstrin homology (PH) and the Fab-1, YOTB, Vac1, and EEA1 (FYVE) domains. The requirement for both domains for binding to PtdIns3P still remains unclear. To understand the molecular interactions of the Phafin2 PH domain in detail, we report its nearly complete ¹H, ¹⁵N, and ¹³C backbone resonance assignments.

期刊介绍： Biomolecular NMR Assignments provides a forum for publishing sequence-specific resonance assignments for proteins and nucleic acids as Assignment Notes. Chemical shifts for NMR-active nuclei in macromolecules contain detailed information on molecular conformation and properties. Publication of resonance assignments in Biomolecular NMR Assignments ensures that these data are deposited into a public database at BioMagResBank (BMRB; http://www.bmrb.wisc.edu/), where they are available to other researchers. Coverage includes proteins and nucleic acids; Assignment Notes are processed for rapid online publication and are published in biannual online editions in June and December.
