Imprecise excision of the progenitor insertion, resulting in a 2673bp deletion (coordinates 2R:6190378..6193141 , release 5 genome) that removes the first two SH3 domain-coding exons.
2764 kb deletion resulting from the imprecise excision of P{PTT-GA}CAPCA06924.
Homozygous and hemizygous larvae do not show a significant hunching response to vibration, in contrast to wild-type controls.
Actin organisation at the muscle attachment site between lateral-ventral somatic muscles 6 and 7 in abdominal segments is severely disrupted in mutant larvae, resulting in a jagged boundary. There is a significantly enlarged gap between actin filaments from adjacent muscles at most muscle attachment sites. Integrin distribution is broader than normal.
