A highly conserved laminin receptor processed pseudogene (LAMRL5) that has been isolated from a fetal brain cDNA library is described. The pseudogene is a complete copy (97.9% identical) of the transcribed laminin receptor (LAMR1) with all the introns precisely removed. The sequence has direct repeats of 18 bp at either end. It has an 885 nucleotide open reading frame from the start methionine codon to the stop codon that contains no deletions, additions or premature stop codons relative to the expressed LAMR1 gene and has the coding potential for a protein of 295 amino acids. Although TATA and CAAT boxes exist in the region 5' to the open reading frame and a polyadenylation signal is present in the 3' region, no evidence could be obtained either by reverse transcriptase-polymerase chain reaction (RT-PCR) or in the expressed sequence tag (EST) database that LAMRL5 is expressed in vivo. If not expressed, it is estimated that this LAMRL5 pseudogene was incorporated into the human genome approximately 3.5-5 million years ago.
