The product of the mouse Rec-1 locus is an integral membrane protein that determines susceptibility to infection by murine ecotropic retroviruses. Recently it has been determined that its role in normal cell metabolism is transport of the cationic amino acids, arginine, lysine, and ornithine across the plasma membrane. Southern blot analysis of genomic DNA from a panel of 48 mouse-human somatic cell hybrids assigned the human version of this gene, ATRC1, to chromosome 13. Chromosomal in situ hybridization localized the gene to 13q12-q14. A restriction fragment length polymorphism (RFLP) was detected with TaqI. There were two alleles with frequencies of 0.29 and 0.71. Pairwise linkage analysis established linkage between ATRC1 and ATP1AL1, D13S1, D13S6, D13S10, D13S11, D13S21, D13S22, D13S33, D13S36, and D13S37. Multilocus linkage analysis of five of the loci indicated that the most likely order of loci in this region was D13S11-ATP1AL1-ATRC1-D13S6-D13S33.

A novel cDNA clone (20.5) which is differentially expressed between two closely related T-lymphoma cell clones was isolated by subtraction-enriched differential screening. SL12.4 cells, from which the cDNA was isolated, have characteristics of thymocytes at an intermediate stage in development. A sister cell clone derived from the same tumor, SL12.3, does not express this mRNA, has a distinct phenotype, and expresses fewer genes required for mature T-cell function. The cDNA sequence predicts a highly hydrophobic protein (approximately 49.5 kilodaltons) which contains seven putative membrane spanning domains. The gene was expressed on concanavalin A-activated T lymphocytes and was designated Tea (T-cell early activation gene). The Tea gene mapped to chromosome 8 and appeared to be conserved among mammalian and avian species. The Tea gene is distinct from, but bears extensive amino acid and DNA sequence similarity with, the murine ecotropic retroviral receptor which is encoded by the Rec-1 gene. Neither gene product displayed significant homology with other known transmembrane-spanning proteins. Thus, the Tea and Rec-1 genes establish a new family encoding multiple membrane-spanning proteins.
