LIG_FHA_2 - Phosphothreonine motif binding a subset of FHA domains that have a preference for an acidic amino acid at the pT+3 position. | |||||||
| XRCC1_HUMAN | 521 | 527 | Binary | Physicochemical compatibility | Phosphorylation of T523 in the FHA-binding motif of DNA repair protein XRCC1 (XRCC1) by Casein kinase II subunit alpha (CSNK2A1) induces binding to the Aprataxin (APTX) protein. | ||
| XRCC1_HUMAN | 517 521 | 523 527 | Cumulative | Rheostatic | Two Bifunctional polynucleotide phosphatase/kinase (PNKP) molecules interact with two FHA-binding motifs in DNA repair protein XRCC1 (XRCC1) upon phosphorylation of T519 and T523 in the motifs. Additional phosphorylation of S518 and S525 further increases the affinity of the interaction. S518 and T523 are consensus CK2 phosphorylation sites, T519 and S525 atypical. | ||
| XRCC1_HUMAN | 517 | 523 | Avidity‑sensing | Hierarchical cooperative binding of two Bifunctional polynucleotide phosphatase/kinase (PNKP) molecules to one DNA repair protein XRCC1 (XRCC1) molecule upon phosphorylation of a primary and secondary FHA-binding motif in DNA repair protein XRCC1 (XRCC1) by Casein kinase II subunit alpha (CSNK2A1). | |||
