Definitions #4 Flashcards
(17 cards)
N-Cam
~ found on surface of neurones + glial cells
~ shows homophobic adhesion via immunoglobulin domains
N-Cadherin
shows homophobic Ca2+ dependent adhesion at each end
Laminin
~ trimetric glycoprotein (alpha, beta, gamma chains) w/ many diff isoforms to give specificity
~ interacts w/ integrin on cell surface which interacts w/actin –> influences growth cone motility
CAMKII
promotes integration of additional AMPA receptors on dendritic spine
How are two types of sensory information integrated in fly brain?
adenyl cyclase performs integration in mushroom body of the fly brain
CS is presented to MB by…
projection neurons
CS=odor
US is presented to MB by…
PPL1/PPL2ab neurons
US=aversive/appetitive stimuli
Name the three layers the prelate is dived into:
1) marginal zone
2) cortical plate
3) subplate
Disabled 1
binds to cytoplasmic tails of reelin receptors and becomes phosphorylated –> causes signalling kinase cascade = change in gene expression and surface properties = migration
Notochord
~ becomes vertebrate + spinal cord
~ moves backwards and under neuroectoderm after gastrulation
Organiser
~ induces gastrulation
~ cells near organiser go on to form notochord
TCF3
transcriptional factor that when bound to beta-catenin promotes transcription of siamois and twin genes
Beta-catenin is (not) degreased in…
degraded = vegetal pole
non degraded = animal pole
Gynandromorph
flies w/ male + female parts
GAL4 protein
transcriptional activator
UAS
a.k.a. upstream activation sequence
~ enhancer specific to GAL4 protein
Octopamine
invertebrate counterpart of noradrenaline
used in appetitive conditioning instead of dopamine
