Supplementary information

The Cytoplasmic Polyadenylation Element Binding Protein 1 (CPEB1) functions mechanically as a regulator of mRNA translation. Often referred to simply as CPEB1 this protein has a mass of approximately 62 kDa. CPEB1 is expressed in various tissues including the brain and ovary indicating its role in diverse physiological processes. It binds to the cytoplasmic polyadenylation element typically found at the 3' untranslated region of mRNAs controlling the length of the poly(A) tail and therefore influencing mRNA stability and translation.
Biological function summary

CPEB1 regulates cell cycle progression synaptic plasticity and gametogenesis. This protein sometimes part of larger ribonucleoprotein complexes acts by coordinating the temporal and spatial translation of target mRNAs. In neurons CPEB1 plays a significant role in the regulation of local protein synthesis impacting synaptic function and plasticity. In reproductive biology it influences oocyte maturation by modulating the translation of mRNAs important for meiotic progression.

Pathways

CPEB1 plays critical roles within pathways associated with long-term potentiation and the cell cycle. In the long-term potentiation pathway CPEB1 works alongside proteins such as eIF2α to enhance synaptic strength and memory formation. In cell cycle regulation CPEB1 affects the translational activation of cyclins thereby controlling the progression through the cell cycle phases. These pathways highlight its involvement in maintaining cellular homeostasis and response to external stimuli.

CPEB1 has been implicated in neurological disorders such as Alzheimer's disease and Fragile X syndrome. In Alzheimer's disease dysregulation of CPEB1 can lead to impaired synaptic function exacerbating cognitive decline. Similarly CPEB1's interaction with FMRP links it to Fragile X syndrome where it influences synaptic plasticity and neuronal development. These associations highlight the importance of CPEB1 in brain health and cognitive functionality.

Target data

Sequence-specific RNA-binding protein that regulates mRNA cytoplasmic polyadenylation and translation initiation during oocyte maturation, early development and at postsynapse sites of neurons. Binds to the cytoplasmic polyadenylation element (CPE), an uridine-rich sequence element (consensus sequence 5'-UUUUUAU-3') within the mRNA 3'-UTR. RNA binding results in a clear conformational change analogous to the Venus fly trap mechanism (PubMed : 24990967). In absence of phosphorylation and in association with TACC3 is also involved as a repressor of translation of CPE-containing mRNA; a repression that is relieved by phosphorylation or degradation (By similarity). Involved in the transport of CPE-containing mRNA to dendrites; those mRNAs may be transported to dendrites in a translationally dormant form and translationally activated at synapses (By similarity). Its interaction with APLP1 promotes local CPE-containing mRNA polyadenylation and translation activation (By similarity). Induces the assembly of stress granules in the absence of stress. Required for cell cycle progression, specifically for prophase entry (PubMed : 26398195).
