Protein Flashcards
Mnemonic for 1st 5 of 28 types of collagen
1 skin
2 connective tissue
3 arteries and other cvs
4 basement membrane of glomeruli(Alport syndrome , hematuria and endstage renal disorder)
7 junction of epidermis and dermis(epidermolysis bulbosa, blisters)
Menkes disease and collagen
Glycosylation via Lysyl oxidase (in presence of Cu+2 )of collagen decreases
Transthyretin
In transport of thyroxine and retinol binding protein
Aka pre albumin
Blood and CSF
Ceruloplasmin
6 Cu binding protein
From liver
For iron transport also as it has ferro oxidase activity
Menkes disease
Protein ATP- 7A defective
Cu transport decreases. Cu decreases in blood and tissue
Brain affected, grey kinky hair
X linked so males are …
Disease in infancy and death in 3 years
All oxidases including lysyl oxidase affected
Wilson’s disease
ATP 7B protein of liver is the defect Cu into bile transport decreases Adds Cu to ceruloplasmin So ceruloplasmin is not properly formed and in low levels Cu deposits in liver, kidney , brain and RBC Cu increases in urine and blood Autosomal recessive Hepatosplenomegaly Haemolytic anaemia Seizures Sunflower cataract Kayser Fleisher rich due to deposits in decement membrane
Selenium deficiency
Keshan disease
Zinc deficiency
Acrodermatitis enterohepatica
