Phosphotyrosine is the phosphorylated version of the amino acid tyrosine. Phosphorylation of histidine, serine, threonine and tyrosine residues acts as a signalling system to control many cellular signalling pathways. The cellular networks which rely on these signals can be very complex, so phosphorylation often occurs on multiple sites on a given protein.
- 2 amino 3(4 hydroxyphenyl) propanoic acid
