The AmCREB gene is an ortholog of the mammalian CREB/CREM family of transcription factors and encodes several splice variants in the honeybee brain.
The transcription factor CREB (cAMP response element binding protein) is required for the switch from short-term to long-term synaptic plasticity and from short-term to long-term memory. Its activity is regulated by the cAMP-dependent signalling cascade, which has been shown to play a crucial role in the honeybee's long-term memory formation. To elucidate the role of the CREB in honeybee memory formation we analysed a CREB-homologous gene, AmCREB, which is expressed as several transcripts in the honeybee brain. Eight transcripts have been identified (AmCREB 1-8) that are generated by alternate splicing. One antibody generated against a subset of these variants reveals a cytosolic localization in the mushroom body alpha-lobes, the glomeruli of the antennal lobes, the protocerebral lobes, the central complex and in the optical lobes.
