Abstract

Although CREB seems to be important for memory formation, it is not known which of the isoforms of CREB, CREM, or ATF1 are expressed in the neurons that undergo long-term synaptic changes and what roles they have in memory formation. We have found a single Aplysia CREB1 gene homologous to both mammalian CREB and CREM and have characterized in the sensory neurons that mediate gill-withdrawal reflex the expression and function of the three proteins that it encodes: CREB1a, CREB1b, and CREB1c. CREB1a is a transcriptional activator that is both necessary and, upon phosphorylation, sufficient for long-term facilitation. CREB1b is a repressor of long-term facilitation. Cytoplasmic CREB1c modulates both the short- and long-term facilitation. Thus, in the sensory neurons, CREB1 encodes a critical regulatory unit converting short- to long-term synaptic changes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
