      It was found that BbKst-kinase is a monomeric kD serine/threonine protein kinase enzyme, phophorylating a broad spectrum of proteins (specifically Casein, MBP, Histone, LRRKtide, GS peptide). All kinases require divalent cations (Mg +2 or Mn +2) to coordinate the phosphate groups of the phosphate donor. Dual-specificty kinases are those than overall belong to Ser/Thr kinase groups, but can also phosphorylate on tyrosine. Several DSKs are well known, though many others may have tyrosine kinase activity at a low level or under specific circumstances. Here is a summary of the reported dual-specificity kinase .

    Mycorrhizal fungi are a heterogeneous group of diverse taxa associated with the roots of over 90% of all plant species, from liverworts to angiosperms. Although they can spend part of their life cycle in the rhizosphere, mycorrhizal fungi always associate with the roots of plants, including forest trees, wild grasses, and many crops, and colonize environments such as alpine and boreal zones. serine/threonine kinases in plant cells appears to act as a “central processor unit” (protein kinase C), and calcium (calmodulin-dependent protein kinases). 2. The response to messenger molecules anchored in the the surface of neigh-boring cells In these cases protein kinases play .

    CK2 is a highly conserved serine/threonine kinase composed of two catalytic subunits (i.e., α and/or α’) and two regulatory β-subunits with the ability to participate in the regulation of a broad range of cellular processes from motility to cell division, survival and metabolism [81,82,83]. Compelling evidence has shown that CK2 is. In biochemistry, a dual-specificity kinase (EC ) is a kinase that can act as both tyrosine kinase and serine/threonine kinase.. MEKs, involved in MAP pathways, are principal examples of dual-specificity common examples include: ADK1; Arabidopsis dual specificity kinase 1; CLK1, CLK2, CLK3, CLK4; DSTYK; DYRK1A, DYRK1B, DYRK2, DYRK3, DYRK4.

The establishment of symbiotic associations in plants requires calcium oscillations that must be decoded to invoke downstream developmental programs.

In animal systems, comparable calcium oscillations are decoded by calmodulin ([CaM][1])–dependent protein kinases, but symbiotic signaling involves a calcium/[CaM][1]–dependent protein kinase ([CCaMK][2]) that is unique to plants. Plant oils are stored in oleosomes or oil bodies, which are surrounded by a monolayer of phospholipids embedded with oleosin proteins that stabilize the structure.

Recently, a structural protein, Oleosin3 (OLE3), was shown to exhibit both monoacylglycerol acyltransferase and phospholipase A2 activities. The regulation of these distinct dual activities in a single protein is unclear. INTRODUCTION. Calcium plays an important role as a second messenger in many developmental and physiological processes in both mammals and plants [1–3].The roles of Ca 2+ are mediated by a group of Ca 2+-binding proteins including CaM (calmodulin) and CDPKs (Ca 2+-dependent protein kinases) [4–6].CaM is ubiquitously expressed and has no enzymic activity of its own.

It was observed that OsCaM61 stimulated OsCBK in a Ca 2+ ‐dependent manner.

Plants have four main types of Ca 2+ sensor proteins to relay or decode Ca 2+ signals: calmodulin (CaM) and CaM‐like proteins (CMLs), calcineurin B‐like proteins (CBLs), Ca 2+ ‐dependent protein kinases (CDPKs or CPKs), and calcium/CaM‐dependent protein kinase (CCaMK).This domain may function in kinase regulation by releasing the autoinhibitory domain Chimeric plant calcium/calmodulin-dependent protein kinase gene with a neural visinin-like calcium-binding domain.
