Negative regulators of STATs include cytoplasmic tyrosine phosphatases that counteract Janus kinase (JAK) action, induced suppressor of cytokine signalling (SOCS) proteins that inhibit receptor and JAK function, proteins that inhibit activated STAT (PIAS) proteins that prevent STAT DNA binding, nuclear phosphatases that deactivate STATs, and truncated STAT proteins that can function in a dominant-inhibitory mode. Like the TCR, CD8 binds to a major histocompatibility complex (MHC) molecule, but is specific for the MHC class I protein.[1]. The C-terminus of proteins can be modified posttranslationally, most commonly by the addition of a lipid anchor to the C-terminus that allows the protein to be inserted into a membrane without having a transmembrane domain.
