该基因编码一个I型细胞因子受体家族成员。编码蛋白是胸腺基质淋巴生成素（TSLP）的受体。与白细胞介素7受体（IL7R）一起，编码蛋白和tslp激活Stat3、Stat5和Jak2途径，这些途径控制细胞增殖和造血系统发育等过程。该基因与14号染色体上的免疫球蛋白重链基因（igh）或同一X或Y染色体上的p2y嘌呤核蛋白8基因（p2ry8）的重排与B祖细胞急性淋巴细胞白血病（all）和唐氏综合征（all）有关。另外，还发现了该基因的剪接转录变体。
This gene encodes a member of the type I cytokine receptor family. The encoded protein is a receptor for thymic stromal lymphopoietin (TSLP). Together with the interleukin 7 receptor (IL7R), the encoded protein and TSLP activate STAT3, STAT5, and JAK2 pathways, which control processes such as cell proliferation and development of the hematopoietic system. Rearrangement of this gene with immunoglobulin heavy chain gene (IGH) on chromosome 14, or with P2Y purinoceptor 8 gene (P2RY8) on the same X or Y chromosomes is associated with B-progenitor acute lymphoblastic leukemia (ALL) and Down syndrome ALL. Alternatively spliced transcript variants have been found for this gene.
