sh domains on proteins have functions please name the functi

Solution

Distinct functional and structural units in proteins are known as domains.

The function of SH2 domains is to specifically recognise the phosphorylated state of tyrosine residues, thus allowing SH2 domain-containing proteins to localise to tyrosine-phosphorylated sites.

SH3 domains arbitrate intracellular protein-protein interactions through the recognition of proline-rich sequence motifs on cellular proteins.
