Biolegend, 322804, Biotin anti-human TSLPR (TSLP-R) Antibody

TSLP-R, also known as the thymic stromal lymphopoietin protein receptor, cytokine receptor-like 2, CRL2, and IL-XR, is a type I membrane receptor that forms a functional heterodimeric complex with IL-7R to bind with TSLP. The TSLP-R contains a WSXWS motif required for proper protein folding and a box1 motif important for association with the JAKs. TSLP-R has a predicted molecular weight approximately 40 kD, and has two isoforms reported that are produced by alternative splicing. The TSLP-R is expressed preferentially in myeloid cells, dendritic cells, and activated monocytes. It is weakly expressed in T cells. Expression has also been reported in heart, skeletal, muscle, and kidney tissues. TSLP binding to the heterodimeric functional receptor (TSLP-R and IL-7R) activates JAK2, STAT3, and STAT5 to stimulate cell proliferation. Ligand receptor interactions have been implicated in the development of the hematopoietic system, dendritic cell maturation, and the maintenance and polarization of human Th2 memory T cells in allergy diseases.
