SH2B adapter protein 1 is a protein that in humans is encoded by the SH2B1 gene.[1][2][3]


SH2B1 has been shown to interact with:

Clinical significance[edit]

Variations close to or in the SH2B1 gene have been found to associatate with obesity in two very large genome wide association studies of body mass index (BMI).[9][10] Furthermore SH2B1 deletions are associated with severe early-onset obesity.[11]
