Have a phosphoserine residue that causes them to bind to other proteins.

Have a phosphotyrosine residue that causes them to bind to other proteins.

Bind to any proteins that have a phosphothreonine group.

Bind to proteins that have a phosphotyrosine residue and a specific conformation.

Binds to proteins that have 2 sulfhydryl groups.

Verified step by step guidance

Understand the role of the SH2 domain: The src homology 2 (SH2) domain is a protein domain that allows proteins to bind to phosphorylated tyrosine residues on other proteins.

Identify the key feature of SH2 domains: SH2 domains specifically recognize and bind to phosphotyrosine residues, which are tyrosine amino acids that have been phosphorylated.

Consider the specificity of SH2 domain binding: The binding is not only dependent on the presence of a phosphotyrosine residue but also on the surrounding amino acid sequence, which provides a specific conformation for binding.

Eliminate incorrect options: SH2 domains do not bind to phosphoserine or phosphothreonine residues, nor do they bind based on the presence of sulfhydryl groups.

Conclude with the correct understanding: SH2 domains bind to proteins that have a phosphotyrosine residue and a specific conformation, which is crucial for signal transduction pathways in cells.
