A malfunction in CFTR's uptake of sugar groups at this site is a primary mutation associated with cystic fibrosis.  
A malfunction in CFTR's uptake of sugar groups at this site is a primary mutation associated with cystic fibrosis.  It recognizes and designates destination based on the presence of a hydrophobic signal sequence or signal recognition particle.  Enclosing a sac known as the lumen, this structure was once known as the gastroplasm.  It consists of two phospholipid bilayers and the presence of ribosomes differentiates its two types.  FTP, name this transport network within the cytoplasm, divided into smooth and rough varieties.
