Interleukin-1 alpha and -1 beta (IL-1 alpha and IL-1 beta) are cytokines that participate in the regulation of immune responses, inflammatory reactions, and hematopoiesis. A direct expression strategy was used to clone the receptor for IL-1 from mouse T cells. The product of the cloned complementary DNA binds both IL-1 alpha and IL-1 beta in a manner indistinguishable from that of the native T cell IL-1 receptor. The extracellular, IL-1 binding portion of the receptor is 319 amino acids in length and is composed of three immunoglobulin-like domains. The cytoplasmic portion of the receptor is 217 amino acids long.
白细胞介素-1α和-1β（IL-1α和IL-1β）是参与免疫反应、炎症反应和造血调节的细胞因子。采用直接表达策略从小鼠T细胞中克隆IL-1受体。克隆的互补DNA产物以与天然T细胞IL-1受体无法区分的方式结合IL-1α和IL-1β。受体的细胞外IL-1结合部分长度为319个氨基酸，由三个免疫球蛋白样结构域组成。受体的细胞质部分长217个氨基酸。
