Gene Variant Descriptions | JAK2 S523L lies within a linker region of the Jak2 protein (PMID: 29685781). S523L results in impaired phosphorylation of Jak2 at S523, a site that negatively regulates Jak2 activity, and demonstrates increased cytokine-independent phosphorylation of Jak2 and Stat5 and cytokine-independent growth in cell culture (PMID: 32956452). |
