Protein Effect | gain of function |
Gene Variant Descriptions | JAK3 I87T lies within the FERM domain of the Jak3 protein (UniProt.org). I87T confers a gain of function to Jak3, as demonstrated by increased Jak3 autophosphorylation (PMID: 29046866), constitutive phosphorylation of downstream Stat5, and is transforming in cell culture (PMID: 18397343). |
