Term
Ciliopathies
Definition

-Polycistic Kidney disease

-Central nervous system defects

-Basal cell carcinoma

-Vision loss

Term
Primary functions of smooth ER
Definition
Makes steroid hormones and lipids
Storage + release of CA
Detoxification of drugs
Term
Histones in sperm cells
Definition
Replaced with protamines
Protamines= arginine-rich -->tighter packaging of DNA
Crucial for sperm head condensation and DNA stability
Term
Dark bands in G-banding
Definition
AT rich, Gene poor (heterochromatin)
Term
Pseudoautosomal region
Definition
Distal p-arm regions of X and Y chromosomes with highly similar DNA sequences where recombination takes place during MI.
Term
MLH1 foci
Definition
Single obligatory site of recombination for both p+q arms including XY.
Term
Motif
Definition
Recognizable folding pattern involving 2 or more elements of 2 structure and the connections between them
Term
Domain
Definition
Regions of protein capable of folding independently and that often have different functions
Term
Type I +II integral membrane proteins
Definition
Single transmembrane helix, N-terminal outside in type II, inside in II.
Term
Type III integral membrane protein
Definition
Multiple transmembrane helices in 1 polypeptide
Term
Type IV integral membrane proteins
Definition
Transmembrane domains of different polypeptides assemble to form a channel through the membrane
Term
Type V integral membrane proteins
Definition
Proteins held to bilayer by covalently linked lipids
Term
Type VI integral membrane proteins
Definition
Both transmembrane helices and lipid anchors
