IFNG dimer binds to receptor contained two IFNGR1 and two IFNGR2 subunits.
PMID:19833085
IFNG receptor is assosiated with kinases JAK1 and JAK2.
Ligand engagement of the IFNG receptor leads to activation of receptor-associated Jak1 and Jak2 and phosphorylation of a receptor tyrosine residue
(Y440) that serves as a docking site for STAT1, which exists in a latent state in the cytoplasm.

TLR signaling can induces STAT1 phosphorylation via p38 and potentiate IFNG signaling.
STAT1 is activated downstream of IFNG by phosphorylation of tyrosine 701, translocates to the nucleus, binds to a regulatory DNA element termed gamma-activated sequence (GAS) and stimulates transcription of STAT1 target genes.
