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. SOCS-1 is a member of family of proteins which negatively regulate cytokine signaling. Bypassing SOCS-1 activity may be an essential step during cellular transformation by Jak-dependent oncogenes. SOCS-1 over expression is unable to inhibit transformation by v-Abl oncogenes that suggests the activity of SOCS-1 is decreased. The Rothman laboratory has evidence that the phosphorylation of SOCS-1 on non-tyrosine residues has a role in modulating the activity of SOCS-1. The determination of the sites of phosphorylation would be very useful in understanding this important regulatory event.

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得主要资金，因此可以在其他CRISP条目中表示。所列机构为中心，不一定是研究者所在机构。SOCS-1是负调节细胞因子信号传导的蛋白质家族的成员。激活SOCS-1活性可能是Jak依赖性癌基因转化细胞过程中的一个重要步骤。SOCS-1过表达不能抑制v-Abl癌基因的转化，这表明SOCS-1的活性降低。Rothman实验室有证据表明SOCS-1在非酪氨酸残基上的磷酸化在调节SOCS-1的活性中起作用。磷酸化位点的确定对于理解这一重要的调控事件是非常有用的。
