Cytology
Description

UAS regulates expression of Syt1 lacking the C2B domain and in which the remaining C2A domain contains D282N and D284N mutations, thus preventing Ca[2+] binding this domain.

      Fails to rescue

      Scer\GAL4elav-C155/Syt1C2A*.UAS fails to rescue Syt1AD4/Syt1N13

      (Lee et al., 2013)
      Comments

      Scer\GAL4elav-C155-mediated expression of Syt1C2A*.Scer\UAS fails to restore synchronous neurotransmitter release (measured as eEJPs) at third instar NMJs in Syt1N13/Syt1AD4 animals at high (1.0mM) external Ca[2+].

      Scer\GAL4elav-C155-mediated expression of Syt1C2A*.Scer\UAS fails to restore spontaneous neurotransmitter release frequency (measured as mEJPs) to control levels at third instar NMJs in Syt1N13/Syt1AD4 animals at low (0.2mM) external Ca[2+].
