Point mutations can result in a protein that can no longer bind to its binding partner, or a catalytically inactive enzyme.
Mutual interactions between HNF4A and TFIID stabilise both PIC formation and CRM occupancy, without PIC formation HNF4A does not stably bind to its binding sites.
While the TALE-Rheo receptor fusion can bind to its DNA target, it lacks an activation domain and thus does not regulate transcription.
We report on the design and characterization of a family of EphA4 targeting agents that bind to its ligand binding domain with nanomolar affinity.
The binding to ssDNA indicates that the protein is correctly folded, as it can bind to its substrate.
Thus, DCN traps TGF- β in the ECM before it can bind to its receptors on the cell surface [ 36].
In an analogous antagonism to TGF- β, DCN sequesters platelet-derived growth factor (PDGF) before it can bind to its receptors on the surface of target cells [ 55].
The new protein seems to bind to its evil sibling, perhaps preventing it from entering cells, Brentani says.
The first and most obvious is that YopJ must bind to its substrate to acetylate and inhibit it.
TGFβ is secreted as an inactive complex and requires activation before it is able to bind to its receptor [ 28].
Possibilities include selective import to the CCC, or possibly selective degradation of RLSB in the PCC if it was unable to bind to its target rbcL mRNA.
