Interacts with CHD7 and CHD8. Expressed strongly in lung, at slightly lower levels in heart, kidney, brain and testis, and weakly in liver (at protein level). In brain, highly expressed in cortex, hippocampus, dentate gyrus, caudate putamen and cerebellum (at protein level). At embryonic stage 12.5 dpc, detected in a wide range of tissues including brain, heart, lung, cochlea, dorsal root ganglia, and liver (at protein level). Belongs to the FAM124 family.
