BLAST analysis of the Drosophila genome sequence from the Berkley Drosophila Genome Sequencing Project identifies three regions of the Drosophila genome with similarity to axonemal dynein intermediate chains (Chlamydomonas IC70 and IC78) as well as to the Drosophila cytoplasmic dynein intermediate chain gene at region 19C (Cdic19C). Amino acid sequences from the known intermediate chain genes were compared with the Drosophila genomic nucleotide sequence with the use of the program TBLASTN. BLAST probability represents the probability that the sequence similarity identified is due to chance. 

^a The completion of the Drosophila genome sequence has identified additional related sequences that may be present at genomic regions 7D, 61A, 66A, and 68C (Adams et al., 2000; Goldstein and Gunawardena, 2000).
