how many diff nucleoporins in a nuclear pore
30
lamina
keep nuclear pores evening spaced
where are lamina found
on the inside of the nuclear envelope
how can lamina importance be established
using DNA technology to turn off the gene for lamina- pores will cluster without
what are the intermediate filaments of nuclear lamina
lamins
when lamina is phosphorylated
nuclear envelope breaks down
nucleomorphs
nuclei in-between inner and outer membrane. vestiges of primitive red and green algae- engulfed
‘DNA relicts f an engulfed eukaryote’
nucleomorphs
F-actin is made out of
G-actin and forms 3 protofilaments
what do oligosaccharides do
- protect against pathogens
- cell-cell recognition
- shows progression of cell
- helps folding and interaction with other proteins
what are oligosaccharides linked to
asparagine and threonine
clathrin coat has
triskelion (3 arms) and needs no proteins to form
when vesicle becomes active
clathrin coat removal and recycling
golgi produces
lysosomes, plasma membrane and secretory vesicles
size of microvesicles
1000-5000nm
where are microvesicles formed
at the donor membrane
size of exosomes
40-100nm
exosome formed at
early endosome, released from late endosome
exosome fuses with target membrane via
futon or endocytosis
formation of lipid droplet
- fatty acid cholesterol build up in inner membrane of ER
- circular organelle formed
- FABP make fatty acid water soluble
preoxisomes
- biosynthesis of cholesterol
- breakdown of long chain fatty act (b-oxidation)
what are inside micro vesicles and exosomes
transfer proteins, mRNA and miRNA
rods and cones are
non-motile primary cilia
detoxification of peroxisomes generate
hydrogen peroxide
