Comparison of NH2-terminal protein sequence from the rat OX-44 antigen with the sequence of the human CD37 antigen deduced from a cDNA clone shows that these antigens are species homologues. The CD37 sequence is 244 amino acids in length and lacks a conventional leader sequence. The molecule is likely to have an NH2-terminal cytoplasmic domain followed by three transmembrane sequences that lie within the first 110 amino acids. The rest of the molecule is hydrophillic and contains three sites for N-linked glycosylation.
将大鼠OX-44抗原的氨基末端蛋白质序列与从cDNA克隆推导的人CD37抗原序列进行比较,结果表明这些抗原是种属同源物。CD37序列长度为244个氨基酸,缺乏传统的前导序列。该分子可能有一个氨基末端胞质结构域,随后是位于前110个氨基酸内的三个跨膜序列。分子的其余部分是亲水的,包含三个N-连接糖基化位点。
