CC -!- FUNCTION: Calcium-dependent protein kinase which acts as a sensor and
CC effector of intracellular Ca(2+) levels probably in part downstream of
CC cGMP-activated PKG kinase (PubMed:7808482). By phosphorylating various
CC proteins, required for microneme secretion and thus merozoite egress
CC from and invasion of host erythrocytes (By similarity). During
CC gametogenesis, essential for the development of both male and female
CC gametes (By similarity). Phosphorylates SERA5 p50 which enhances SERA5
CC p50 protease activity; however, SERA5 p50 protease activity has been
CC shown in other studies to be controversial. Probably by phosphorylating
CC SERA5 p50, plays a role in merozoite egress from host erythrocytes.
CC Probably prior or during merozoite invasion of host erythrocytes,
CC phosphorylates rhoptry protein RhopH3 which is required for RhopH3
CC localization to rhoptries and for its secretion. Probably in late
CC schizonts, phosphorylates myosin A tail domain-interacting protein MTIP
CC and glideosome-associated protein 45 GAP45, both of which are
CC components of the motor complex that generates the force required by
CC the parasite to invade host cells. In late schizonts, phosphorylates
CC inner membrane complex protein IMC1g. In late schizonts, phosphorylates
CC PKA regulatory subunit PKAr in a calcium-dependent manner, which may
CC contribute to the dissociation of regulatory PKAr and catalytic PKAc
CC subunits and promote the activation of PKAc. May phosphorylate raf
CC kinase inhibitory protein RKIP which in turn may regulate CDPK1
CC catalytic activity (By similarity). May phosphorylate proteins of the
CC host erythrocyte membranes (PubMed:7808482).

CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000269|PubMed:7808482};
CC Note=Can use both Mg(2+) and Mn(2+) in vitro and shows higher activity
CC with Mn(2+) but Mg(2+) is likely to be the in vivo cofactor.
CC {ECO:0000269|PubMed:7808482};
CC -!- ACTIVITY REGULATION: Activated by calcium (PubMed:8440720,
CC PubMed:8142371, PubMed:7808482). Upon calcium binding to the EF-hand
CC domains, the C-terminus of the junction domain (J domain) undergoes a
CC conformational change which results in the dissociation of the pseudo-
CC substrate inhibitory motif from the catalytic domain (By similarity).
CC This, in turn may facilitate the autophosphorylation of the activation
CC loop at Thr-231, which leads to the kinase activation (By similarity).
CC Inhibited by calmodulin antagonists such as calmidazolium,
CC trifluoperazine, N-[6-aminohexyl]-5-chloro-1-naphthalene-sulfonamide,
CC and ophiobolin A (PubMed:7808482). {ECO:0000250|UniProtKB:P62344,
CC ECO:0000269|PubMed:7808482, ECO:0000269|PubMed:8142371,
CC ECO:0000269|PubMed:8440720}.
CC -!- SUBUNIT: Monomer. Forms a high molecular weight (250 and 400 kDa)
CC complex. Forms a complex composed of CDPK1, PKA regulatory subunit PKAr
CC and 14-3-3I; the complex is formed in merozoites in response to low
CC extracellular level of K(+) and may play a role in microneme secretion.
CC Interacts (when phosphorylated) with 14-3-3I in a Ca(2+)-independent
CC manner; the interaction does not regulate CDPK1 catalytic activity but
CC is required for merozoite invasion of host erythrocytes. Interacts with
CC PKA regulatory subunit PKAr; in a Ca(2+)-dependent manner. Interacts
CC with SERA5 p50 in the late schizont stage. Interacts with inner
CC membrane complex protein IMC1g in late schizonts. Interacts with
CC rhoptry protein RhopH3 in merozoites. {ECO:0000250|UniProtKB:P62344}.

CC {ECO:0000250|UniProtKB:P62344}. Note=Localizes to the host erythrocytic
CC membrane at low level (PubMed:7808482). Localizes to the cell membrane
CC in the nascent merozoites contained within the late-stage schizonts and
CC in free merozoites. Colocalizes with MTIP around developing merozoites
CC in segmented schizonts, also localizes in membranes around the mature
CC food vacuole/residual body of the schizonts. Ser-64 phosphorylated form
CC localizes at the apical pole in punctate structures in merozoites
CC within late schizonts in free merozoites. In trophozoites and
CC schizonts, localizes to the parasitophorous vacuole (PV) and in
CC membranous systems derived from the PV including intraparasitic
CC vacuoles and the tubovesicular system, an extension of the
CC parasitophorous vacuole membrane into the host cell cytoplasm.
CC Localization to the cytoplasm in trophozoite or schizonts is minimal
CC (By similarity). In female stage V gametocytes and gametes, localizes
CC to the cell membrane. In stage V male gametocytes, localizes to the
CC cell membrane and in the cytoplasm. In male gametes, localizes to the
CC residual body, cell membrane and in the flagella (By similarity).
CC Calcium and/or autophosphorylation does not affect membrane
CC localization (By similarity). {ECO:0000250|UniProtKB:A0A2I0BVG8,
CC ECO:0000250|UniProtKB:P62344, ECO:0000269|PubMed:7808482}.
CC -!- DEVELOPMENTAL STAGE: Expressed in ring and schizont stages and to a
CC lesser extent in early and late trophozoite stages.
CC {ECO:0000269|PubMed:7808482}.
CC -!- DOMAIN: The junction domain (J domain) is composed of 2 motifs that
CC maintain the kinase inactive. The N-terminal autoinhibitory motif acts
CC as a pseudosubstrate inhibiting the catalytic domain while the C-
CC terminal motif binds the EF-hand domains.
CC {ECO:0000250|UniProtKB:P62344}.
CC -!- PTM: Myristoylated. Myristoylation, palmitoylation and the basic
CC cluster motif are required for the localization to the parasitophorous
CC vacuole membrane. {ECO:0000250|UniProtKB:P62344}.
CC -!- PTM: Palmitoylated. Palmitoylation increases in merozoites in response
CC to low level of extracellular K(+) in the host blood. Myristoylation,
CC palmitoylation and the basic cluster motif are required for the
CC localization to the parasitophorous vacuole membrane.
CC {ECO:0000250|UniProtKB:P62344}.
CC -!- PTM: Phosphorylation at Ser-64 occurs at late schizont stage and
CC regulates CDPK1 protein-protein interaction. Phosphorylated at Ser-28,
CC Ser-34 and Ser-64 in merozoites in response to low extracellular level
CC of K(+). Phosphorylation at Thr-231 may regulate CDPK1 kinase activity.
CC Phosphorylation increases in response to an increase in intracellular
CC Ca(2+) levels (By similarity). Autophosphorylated in vitro
CC (PubMed:7808482). Autophosphorylation does not affect membrane
CC localization in vitro (By similarity). {ECO:0000250|UniProtKB:P62344,
CC ECO:0000269|PubMed:7808482}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. Ser/Thr protein
CC kinase family. CDPK subfamily. {ECO:0000255|PROSITE-ProRule:PRU00159}.
