Human LPAP (lymphocyte phosphatase associated phosphoprotein) and its mouse homologue, CD45-AP (CD45 associated protein) or LSM-1, represent 32- and 30-kDa transmembrane phosphoproteins that noncovalently associate with the tyrosine phosphatase CD45, a key molecule involved in T- and B-lymphocyte activation. Here we report the isolation and sequencing of genomic clones of the human and mouse genes. LPAP (HGMW-approved symbol PTPRCAP) maps to human chromosome 11q13, distal to the BCL-1 breakpoint, and mouse CD45-AP/LSM-1 maps to Chromosome 19B. Both genes span 3 kb and consist of two exons that are separated by a 1.2-kb intron. The promoter regions do not contain TATA boxes, but possess consensus transcriptional initiator sequences that have also been described for other TATA-less genes. The genomic sequences also provide a genetic basis for two different cDNAs (termed CD45-AP and LSM-1, respectively) that have been described in the mouse system.

UI MeSH Term Description Entries
D007438 Introns Sequences of DNA in the genes that are located between the EXONS. They are transcribed along with the exons but are removed from the primary gene transcript by RNA SPLICING to leave mature RNA. Some introns code for separate genes.

D008565 Membrane Proteins Proteins which are found in membranes including cellular and intracellular membranes. They consist of two types, peripheral and integral proteins. They include most membrane-associated enzymes, antigenic proteins, transport proteins, and drug, hormone, and lectin receptors.
