We discuss the connection of γ-ray events to the superluminal component ejection in the jet of the blazar 1156+295. The broadband variability of the source is analysed using multifrequency observations (X-ray through mm single-dish) and radio band imaging data at 43 GHz from Very Long Baseline Array (VLBA) observations. The kinematics of the jet over the interval 2007.0-2012.5, reveal the presence of four moving and one stationary component in the inner region of the blazar jet. The propagation of the third and fourth components in the jet corresponds closely in time to the active phase of the source in γ rays. The physical signatures of these components allowed us to constrain the γ-ray emitting region in the parsec-scale jet.
