CLASS III RECEPTOR TYROSINE KINASES THAT BIND HELICAL-BUNDLE LIGANDS

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目及 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 跨膜受体缺陷/功能障碍经常导致或促成癌症。调节这些受体有望开发癌症疗法，但需要了解激素/生长因子如何通过这些受体起作用。KIT是干细胞因子（SCF）的受体，对人类至关重要。试剂盒故障与胃肠道间质瘤、生殖细胞肿瘤和急性髓性白血病有关。阐明KIT和SCF之间的相互作用机制可能为开发针对KIT相关癌症的策略提供途径。我们建议从结构和功能两方面研究KIT/SCF的相互作用。使用X射线衍射，我们正在获得高分辨率的KIT/SCF复合物的原子图像。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Transmembrane receptor defects/malfunctions frequently cause or contribute to cancer. Modulating these receptors holds promises for developing cancer therapies, but understanding how hormones/growth factors act through these receptors is required. KIT, the receptor for Stem Cell Factor (SCF), is essential for humans. Kit malfunctioning is associated with gastrointestinal stromal tumors, germ cell tumors and acute myeloid leukemia. Elucidating the interaction mechanism between KIT and SCF may provide avenues for developing strategies against KIT-related cancers. We propose to study the KIT/SCF interactions both structurally and functionally. Using X-ray diffraction, we are in progress of getting high-resolution atomic images of the KIT/SCF complex.
