Which sequence correctly describes the JAK-STAT signaling pathway?

Cytokine binds to receptor, JAK is recruited, STAT is phosphorylated, gene expression is altered

Cytokine binds to receptor, adenylate cyclase is activated, cAMP is produced, gene expression is altered

Cytokine binds to receptor, calcium is released, calmodulin is activated, gene expression is altered

Cytokine binds to receptor, DAG is produced, PKC is activated, gene expression is altered
