PA1-1100 detects recombit mouse and rat CPEB (cytoplasmic polyadenylation element binding protein). PA1-1100 has been successfully used in Western blot, ICC/IF and IHC-P procedures. By Western blot, this antibody detects ~62 and kDa protein representing recombit mouse CPEB. The PA1-1100 immunogen is a synthetic peptide corresponding to residues C H(545) S M E G L R H H S P L M R N Q K N(562) of human CPEB. This sequence is completely conserved in mouse. The PA1-1100 immunizing peptide (Cat. No. PEP-171) is available for use in neutralization and control experiments.

CPEB1 is an RNA binding protein that contains an RNA-recognition motif and a zinc finger-containing region found in a wide range of vertebrates and invertebrates. CPEB1 forms the nucleus of a complex of factors that regulate poly(A) elongation and promotes polyadenylation-induced translation. CPEB1 mediates many diverse biological processes such as germ cell development, cell division and senescence, and synaptic plasticity. Recently, it was discovered that CPEB1 is involved in beta-catenin mRNA translation and cell migration in astrocytes as well as regulating hypoxia-inducible factor (HIF)-1 expression, demonstrating the wide range of processes in which CPEB1 plays a role. At least four isoforms of CPEB1 are known to exist.
