چکیده

We have characterized a Drosophila gene that is a highly conserved homolog of the mammalian cyclic AMP (cAMP)-responsive transcription factors CREB and CREM. Uniquely among Drosophila genes characterized to date, it codes for a cAMP-responsive transcriptional activator. An alternatively spliced product of the same gene is a specific antagonist of cAMP-inducible transcription. Analysis of the splicing pattern of the gene suggests that the gene may be the predecessor of the mammalian CREB and CREM genes.

The PKA-CREB system encoded by the honeybee genome

The cAMP-dependent kinase (PKA) plays a crucial part in long-term memory formation in the honeybee (Apis mellifera). One of the putative substrates of the PKA activity is the cAMP response element binding protein (CREB), a transcription factor in the bZIP protein family. We searched the honeybee genome to characterize genes from the CREB/CREM and the PKA families. We identified two genes that e...

Multiple mRNA isoforms of the transcription activator protein CREB: generation by alternative splicing and specific expression in primary spermatocytes.

We have characterized cDNA clones representing mouse CREB (cyclic AMP responsive element binding protein) mRNA isoforms. These include CREB delta and CREB alpha, of which the rat and human homologues have been previously identified. Both encode proteins with CRE-binding activity and identical transactivation potential. The additional CREB mRNA isoforms potentially encode CREB related proteins. ...

A Struggle Against Forgetting

One of the most remarkable characteristics of living organisms is their ability to alter their behavior by learning. Human beings excel at processing new information, retaining it in their memory, and using it to develop new ideas. Studies in the mollusk Aplysia showed that learning involves the strengthening and increased effectiveness of preexisting synapses. Over time, it has become clear th...

Human CREM gene: evolutionary conservation, chromosomal localization, and inducibility of the transcript.

The CREM (cyclic AMP-responsive element modulator) gene encodes multiple regulators of the cyclic AMP transcriptional response. CREM expression has been linked with several key physiological aspects of neuroendocrine pathways. We investigated the conservation of CREM during evolution. Here, we show conservation of CREM sequences in the pig, humans, the chicken, the lemur, and Xenopus. We have a...
