| abstractText | The mouse homolog of a novel human protein tyrosine kinase encoding gene, A6, was cloned and characterized. The human A6 cDNA is unique in that its gene product exhibited in vitro kinase activity but its predicted amino acid (aa) sequence revealed no consensus motifs commonly found within the kinase domain of protein kinase family members. Here, we isolated a mouse A6 cDNA clone from a murine myeloid progenitor 32D cell library using a 1.1 kb cDNA probe containing the entire human A6 open reading frame (ORF). Determination of the mouse A6 cDNA nucleotide (nt) sequence revealed an ORF of 1050 nt encoding a protein of 350 aa and a molecular mass of 40 201 Da. The mouse and human A6 gene products shared 93% identity. In vitro translation, as well as immunoprecipitation of 32D cell lysates confirmed expression of mouse A6 as a 40 kDa protein. Northern blot analysis of total RNA from mouse cell lines derived from diverse tissues including NIH 3T3 fibroblasts, L cell fibroblasts, C2C12 myoblasts, M1 myeloblasts, BALB/MK cells, 70Z/3 preB lymphocytes, and p388D(1) monocytes demonstrated widespread A6 mRNA expression. A6 mRNA was also ubiquitously expressed at varying levels in all tissues examined. The identification of a potential actin/phosphoinositide binding domain and consensus phosphorylation sites, coupled with A6's expression in a variety of cell types suggest that the A6 gene product may play a role in basic cellular processes.
