The phrase "are necessary for binding" is correct and usable in written English.
It can be used in contexts where you are discussing requirements or conditions that must be met for something to be bound or connected.
Example: "The following components are necessary for binding the document securely."
Alternatives: "are essential for binding" or "are required for binding".
Among the newly detected Jun-associated protein candidates, Cebpg, Creb3, and Tef are intriguing proteins as Jun-associated transcriptional regulators, because they contain basic regions near the leucine heptad motifs, which are necessary for binding with regulatory sequences on the genomic DNA; many known Jun-associated proteins contain such structures.
On the other hand, it also partially impedes the interactions that are necessary for binding the nucleic acid to Nop16 by stereological impediment.
The hydrophilic sequences within the N-terminal tail of UCP3, which faces the intermembrane space, are necessary for binding to Trx2.
Three independent site-directed mutagenesis studies have been carried out to determine which residues are necessary for binding to MPL, based on 3D structural data [ 20- 22].
The latter are necessary for binding endothelial cell E-selectin, and their deficiency results in a tumour cell endothelial cell aversion.
Because c-Myc/Max heterodimers are necessary for binding E-box DNA in the target gene, the interruption of their association inhibits the transcriptional function of c-Myc [ 21].
The putative path for RNA agrees well with biochemical data indicating that a 3′ single strand overhang of 7 10 nt is necessary for binding and hydrolysis by RNase II.
In contrast, LigB repeat 9 was necessary for binding fibronectin and its N-terminal fragment.
The 5' stem-loop structure (stem 1) is necessary for binding HEXIM1, which is a prerequisite for binding P-TEFb; in the next step, the 3'-terminal hairpin of 7SK (stem 4; [57]) interacts with P-TEFb [37].
Indeed osteoclastogenic SCs express intercellular adhesion molecule-1 (ICAM-1) which is necessary for binding to OC precursors [39], while matrix-producing osteoblastic cells are ICAM-1 negative [40].
The Roc NH2-terminus is necessary for binding to Cullin protein [26] and forms a β-strand that makes an inter-molecular β-sheet with the Cullin protein [11], [14].
