amino acid sequence
any continuous part of a peptide/protein
signal peptide
short peptide (usually 16-30 amino acids long) present at the N-terminus of the majority of newly synthesized proteins that are destined towards the secretory pathway
fragment crystallizable region
tail region of an antibody
protein subunit
single protein molecule that assembles with other protein molecules to form a protein complex
protein domain
conserved part of a protein
nuclear export signal
amino acid sequence causing a protein to be exported from the nucleus to the cytoplasm
Short linear motif
stretch of protein sequence that mediates protein–protein interaction
framework region
part of antibodies
complementarity determining region
part of the variable chains in immunoglobulins (antibodies) and T cell receptors, generated by B-cells and T-cells respectively
nuclear localization sequence
type of amino acid sequence
Low complexity regions in proteins
unusual regions in protein sequences
protein primary structure
the full linear sequence of amino acids of a peptide or protein
