Related Product Information for anti-PTF1A antibody

Ptf1a is a component of the pancreas transcription factor 1 complex (PTF1) and is known to have a role in mammalian pancreatic development. The protein plays a role in determining whether cells allocated to the pancreatic buds continue towards pancreatic organogenesis or revert back to duodenal fates. This protein is thought to be involved in the maintenance of exocrine pancreas-specific gene expression including elastase 1 and amylase. Mutations in the Ptf1a gene cause cerebellar agenesis and loss of expression is seen in ductal type pancreas cancers.

This gene encodes a protein that is a component of the pancreas transcription factor 1 complex (PTF1) and is known to have a role in mammalian pancreatic development. The protein plays a role in determining whether cells allocated to the pancreatic buds continue towards pancreatic organogenesis or revert back to duodenal fates. The protein is thought to be involved in the maintenance of exocrine pancreas-specific gene expression including elastase 1 and amylase.

Uniprot Description

Function: Transcriptional activator. Binds to the E-box consensus sequence 5'-CANNTG-3'. Plays an important role in determining whether cells allocated to the pancreatic buds continue towards pancreatic organogenesis or revert back to duodenal fates. May be involved in the maintenance of exocrine pancreas-specific gene expression including ELA1 and amylase. Required for the formation of pancreatic acinar and ductal cells

By similarity. Plays an important role in cerebellar development. Ref.2

Subunit structure: Component of the pancreas transcription factor 1 complex (PTF1) which is composed of TCF3/p75, TCF12/p64 and PTF1A/p48. TCF3 is responsible for the nuclear import of the p48/p64 complex. Interacts with TCF3 and RBPSUH/RBP-Jkappa

By similarity.

Subcellular location: Nucleus

By similarity. Cytoplasm

By similarity. Note: In chronic pancreatitis associated with pancreas cancer preferentially accumulates in the cytoplasm of acinar/ductular complexes. In the cytoplasm loses its ability to form the PTF1 complex

By similarity. Ref.2

Tissue specificity: Pancreas-specific (at protein level). Loss of expression is seen in ductal type pancreas cancers. Ref.2

Involvement in disease: Pancreatic and cerebellar agenesis (PACA) [MIM:609069]: A disease characterized by neonatal diabetes mellitus, cerebellar agenesis or hypoplasia, severe intrauterine growth retardation, the presence of very little subcutaneous fat, and dysmorphic facial features.Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.4

Miscellaneous: An excellent marker of acinar cell differentiation in the pancreas.

Sequence similarities: Contains 1 bHLH (basic helix-loop-helix) domain.
