Mutation in the 5' UTR, resulting in a putative early initiation causing a frame-shift.
Nucleotide substitution: A?G.
bondZ3437 mutants exhibit male sterility with cytokinesis defects.
Mutant males have round spermatids containing two to four nuclei associated with an abnormally large mitochondrial derivative.
Constriction of the contractile ring is often minimal or slowed in bondZ5274/bondZ3437 and homozygous bondZ3437 spermatocytes, with these cells ultimately failing to complete cytokinesis. The contractile rings eventually detach from the plasma membrane in the mutant spermatocytes, with the cleavage furrow regressing rapidly and the poorly constricted ring constricting or collapsing rapidly and directionally from the site of membrane detachment towards the opposite site of the cell, where the ring remains attached to the cell cortex.
bondZ3437 has male sterile phenotype, suppressible | partially by Pex2HP35039/CG7081[+]
bondZ3437 has abnormal cytokinesis phenotype, suppressible | partially by Pex2HP35039/CG7081[+]
A pex2HP35039/+ background partially suppresses the male sterility and cytokinesis defects found in bondZ3437 mutants.
