Receptorium acetylcholini M1 (M1R) est receptorium muscarinium et proteino G copulatum. In hominibus genum eius in chromosomate 11 locatum est. Nomen geni est CHRM1.
Receptoria M1 imprimis in systemate nervoso centrali inveniuntur, quare ea subtypi neuronales vocitantur[1].
Multae antagonistae notae sunt, inter eas etiam medicamenta ut Olanzapinum, Quetiapinum.
Physiologia[recensere | fontem recensere]
M1 muscarinicum acetylcholini receptorium (M1 mAChR) cum proteino Gαq coniuncta sunt[2], receptorium proteino G copulatum. Stimulatum quasdam kinases ut proteini kinases C (PKC) et A (PKA), velut GPTases parvas (RAS, proteinum G parvum) incitat. Ita activatae et proteini kinases et GPTases epitonia molecularia quoque agunt.
Proteina G, proteinum Gα et subunitas q suum[recensere | fontem recensere]
Conferatur pagina principalis Proteinum G.Inveniuntur heterotrimerica (subunitatibus α, β, γ) proteina cum Gα superficie interna intracellulari[3]. Proteina G epitonia molecularia simplicia videri possunt: Stimulatum enim proteinum statum suum brevis temporis mutant. Dissoluta ab heterodimericis subunitatibus β et γ, subunitas α (Gαq) communiter cum phospholipasi Cβ agit[4].
Proteini kinases C (PKC) et A (PKA)[recensere | fontem recensere]
PKC sunt familia kinasum, quae proteinis positionibus aminoacidorum et serini et threonini greges phosphati dant. PKA prasentiae cyclici adenosini triphosphati (cAMP) pendet.

Inveniuntur receptoria M1
- in glandulis salivariis, quamquam receptoria M3 abundiora sunt[5]
