1

N-Cam

~ found on surface of neurones + glial cells
~ shows homophobic adhesion via immunoglobulin domains

2

N-Cadherin

shows homophobic Ca2+ dependent adhesion at each end

3

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

4

CAMKII

promotes integration of additional AMPA receptors on dendritic spine

5

How are two types of sensory information integrated in fly brain?

adenyl cyclase performs integration in mushroom body of the fly brain

6

CS is presented to MB by...

projection neurons
CS=odor

7

US is presented to MB by...

PPL1/PPL2ab neurons
US=aversive/appetitive stimuli

8

Name the three layers the prelate is dived into:

1) marginal zone
2) cortical plate
3) subplate

9

Disabled 1

binds to cytoplasmic tails of reelin receptors and becomes phosphorylated --> causes signalling kinase cascade = change in gene expression and surface properties = migration

10

Notochord

~ becomes vertebrate + spinal cord
~ moves backwards and under neuroectoderm after gastrulation

11

Organiser

~ induces gastrulation
~ cells near organiser go on to form notochord

12

TCF3

transcriptional factor that when bound to beta-catenin promotes transcription of siamois and twin genes

13

Beta-catenin is (not) degreased in...

degraded = vegetal pole
non degraded = animal pole

14

Gynandromorph

flies w/ male + female parts

15

GAL4 protein

transcriptional activator

16

UAS

a.k.a. upstream activation sequence
~ enhancer specific to GAL4 protein

17

Octopamine

invertebrate counterpart of noradrenaline
(used in appetitive conditioning instead of dopamine)
