Description

Amino acid replacement: T259A.

(Wall et al., 2021)

The endogenous TER94 gene has been replaced with a sequence containing a T259A mutation (equivalent to T262A in human VCP, which is pathogenic), together with a C-terminal sfGFP tag incorporated before the stop codon and a "3xP3-DsRed" selectable marker.

Amino acid change:

T259A | TER94-PA; T284A | TER94-PC; T217A | TER94-PD; T284A | TER94-PE

Reported amino acid change:

T259A

Comment:

Analogous T262A mutation in human VCP implicated in FTDALS6 and/or IBMPFD1 (MSP-1) disease; mutation carried on in vitro construct; site of nucleotide substitution in fly gene inferred by FlyBase curator based on reported amino acid change.

      Reference

      TER94T259A.sfGFP heterozygotes show a progressive decrease in climbing ability in males only. Their larval body wall muscles are disorganized and show smaller nuclei with disorganized lamina, and show lysosomal defects.
