Detailed Description

Statement

Reference

Fak^N30/Fak^K24 larvae show an increase in bouton number per muscle area at the neuromuscular junction compared to wild type.

(Tsai et al., 2012)

At 22[o]C, Fak^N30/Fak^K24 larvae have enlarged neuromuscular junctions (NMJs) (increased bouton number per muscle area) compared to controls. When reared at 29[o]C, the mutant larvae show no further increase in NMJ size, in contrast to wild-type controls, which show enlarged NMJs at 29[o]C compared to at 22[o]C. The mutant larvae do not show an increase in NMJ size after 8 hours food deprivation, in contrast to controls.

(Tsai et al., 2012)

The neuromuscular junction is overgrown compared to wild type in Fak^N30/Fak^K24 third instar larvae. The number of boutons per muscle area and NMJ length per muscle area are increased (by 44% and 22% respectively) compared to wild type. There is a reduction in secondary branches and an increase in higher-order branches at the muscle 6/7 NMJ compared to wild type.

The amplitude and frequency of the miniature excitatory junctional potential (mEJP) is normal at the Fak^N30/Fak^K24 neuromuscular junction. However, the mean amplitude of the evoked EJP is significantly increased compared to wild type.

Genetic Interactions

Statement

Reference

Fak^N30/Fak^KG00304 ; Nf1^E2/+ and rut¹/+ ; Fak^N30/Fak^KG00304 larvae show an increase in bouton number per muscle area at the neuromuscular junction compared to wild type.

Expression of Nf1^{Scer\UAS.T:Avic\GFP-CFP} under the control of Scer\GAL4^elav.PU rescues the neuromuscular junction overgrowth phenotype seen in Fak^N30/Fak^K24 larvae.

The neuromuscular junction overgrowth phenotype seen in Fak^N30/Fak^K24 larvae is unaffected if the larvae are also hemizygous for rut¹.

(Tsai et al., 2012)

Significant overgrowth of the neuromuscular junction (NMJ) (increased bouton number per muscle area and increased NMJ length per muscle area) is seen in Fak^N30/Fak^KG00304 third instar larvae which are also heterozygous for one of βInt-ν¹, scb², Src42A^E1 or Src64B^PI.

Significant overgrowth of the NMJ (increased bouton number per muscle area) is seen in LanA^9-32/+ Fak^N30/Fak^KG00304 third instar larvae.

No significant overgrowth of the neuromuscular junction is seen in Fak^N30/Fak^KG00304 third instar larvae which are also heterozygous for one of mew¹, if^k27e, mys¹ or wb^4Y18.

The overgrowth at the NMJ (increased bouton number per muscle area) seen in Fak^N30/Fak^K24 third instar larvae is enhanced if they are also carrying both Src42A^E1/+ and Src64B^PI/+.

Comments

The neuromuscular junction defects seen in Fak^N30/Fak^K24 larvae are rescued by expression of Fak^{Scer\UAS.T:Ivir\HA1} under the control of Scer\GAL4^elav.PU, but not under the control of Scer\GAL4^Mhc.PW.
