| abstractText | We have recently cloned the gene responsible for the mouse neurological disorder dystonia musculorum. The predicted product of this gene, dystonin (Dst), is a neural isoform of bullous pemphigoid antigen 1 (Bpag1) with an N-terminal actin binding domain, Here we report on the cloning and characterization of mouse ACF7, Sequence analysis revealed extended homology of mACF7 with both the actin binding domain (ABD) and the Bpag1 portions of dystonin. Moreover, mACF7 and Dst display similar isoform diversity and encode similar sized transcripts in the nervous system. Phylogenetic analysis of mACF7 and dystonin ABD sequences suggests a recent evolutionary origin and that these proteins form a separate novel subfamily within the beta- spectrin superfamily of actin binding proteins, Given the implication of several actin binding proteins in genetic disorders, it is important to know the pattern of mACF7 expression. mACF7 transcripts are detected principally in lung, brain, spinal cord, skeletal and cardiac muscle, and skin. Intriguingly, mACF7 expression in lung is strongly induced just before birth and is restricted to type II alveolar cells. To determine whether spontaneous mutants that may be defective in mACF7 exist, we have mapped the mACP7 gene to mouse chromosome 4. (C) 1996 Academic Press, Inc. |
