Type: Specificity Subtype: Domain hiding | |||||||
A domain can be sterically masked by binding of an effector when there is a large difference in intrinsic affinity of the domain for different binding partners, or a large difference in the local abundance of these partners, thereby precluding further interactions of the domain. Binding of the masking molecule can be PTM-dependent or -independent. | |||||||
MEI2_SCHPO | LIG_14-3-3_1;ELM | 435 523 | 440 529 | Binding of meiRNA meiotic non-coding RNA (meiRNA) to the RRM domains of Meiosis protein mei2 (mei2) is essential for promotion of premeiotic DNA synthesis and meiosis I and is blocked by Pat1-mediated phosphorylation-induced binding of the 14-3-3 protein DNA damage checkpoint protein rad24 (rad24) to 2 14-3-3 binding motifs in mei2 | |||
Type: Avidity‑sensing Subtype: | |||||||
Multiple low-affinity interactions give rise to high-avidity interactions that have increased binding strength, with more than additive affinity. | |||||||
