Abstract:
:Based on two partial cDNA sequences, a full-length cDNA sequence for an actin-binding like protein previously named ABPL has been isolated and characterized. ABPL is homologous to the human actin-binding proteins ABP-280 and ABP-278. The predicted sequence for ABPL is 2,705 amino acids in length with a calculated molecular mass of 289 kDa. It contains an amino terminal actin-binding domain followed by 24 tandem repeats of approximately 96 amino acids. Two hinge regions, Hinge I and Hinge II, were located prior to repeats 16 and 24, respectively. An isoform of ABPL lacking Hinge I, with a calculated molecular mass of 286 kDa, was also identified by the reverse transcriptase PCR (RT-PCR) method. A comparison with genomic sequences indicated the isoform resulted from alternative RNA splicing. ABPL has a unique insertion sequence of 82 amino acids in repeat 20 that was not present in the other two homologues and has a tissue distribution that was also different from the other two homologues.
