Cloning and Identification of a Novel cDNA1 Which May Be Associated with FKBP25

摘要

A 1209 bp novel cDNA with a putative open reading frame of 627 bp that has an overlapped fragment of 527 bp with FKBP25 was isolated from a human fetal brain library. Northern Blot analysis detected a signal about 1.5 kb that suggests it is a full-length cDNA. Reverse transcription-PCR demonstrates that the transcripts are high in adult brain, testis, ovary, spleen, and fetal brain. Comparing the cDNA with the human genome database identifies a contig that reveals that the gene contains six exons and is located on human chromosome 20p11. The gene encodes a putative protein with an unknown domain conserved in many species and is similar to bacterial histidyl-tRNA synthetase, and so it is named human histidyl-tRNA-synthetase-related gene.
