Related Product Information for anti-STN1 antibody
The yeast homolog of OBFC1 is Stn1, which plays a critical role in telomere regulation. OBFC1/AAF44 can localize to telomeres in human cells and bind to telomeric single-stranded DNA in vitro. Overexpression of an OBFC1 mutant resulted in elongated telomeres in human cells, implicating OBFC1/AAF4 in telomere length regulation. OBFC1/AAF44 represents a new player in the telomere interactome for telomere maintenance.

NCBI Description

OBFC1 and C17ORF68 (MIM 613129) are subunits of an alpha accessory factor (AAF) that stimulates the activity of DNA polymerase-alpha-primase (see MIM 176636), the enzyme that initiates DNA replication (Casteel et al., 2009 [PubMed 19119139]). OBFC1 also appears to function in a telomere-associated complex with C17ORF68 and TEN1 (C17ORF106; MIM 613130) (Miyake et al., 2009 [PubMed 19854130]).[supplied by OMIM, Nov 2009]

Uniprot Description

OBFC1: Component of the CST complex, a complex that binds to single-stranded DNA and is required to protect telomeres from DNA degradation. The CST complex binds single-stranded DNA with high affinity in a sequence-independent manner, while isolated subunits bind DNA with low affinity by themselves. In addition to telomere protection, the CST complex has probably a more general role in DNA metabolism at non-telomeric sites. Belongs to the STN1 family.

Chromosomal Location of Human Ortholog: 10q24.33

Cellular Component: nucleoplasm; intermediate filament cytoskeleton; intracellular membrane-bound organelle; nuclear chromosome, telomeric region; nucleolus; nucleus

Molecular Function: protein binding; single-stranded telomeric DNA binding; single-stranded DNA binding

Biological Process: telomere maintenance; positive regulation of DNA replication

Product Notes

The STN1 obfc1 (Catalog #AAA8101451) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Anti-OBFC1 Antibody, Rabbit Polyclonal reacts with Human Predicted to React with: Human, (Species predicted to react based on 100% sequence homology) and may cross-react with other species as described in the data sheet. AAA Biotech's OBFC1 can be used in a range of immunoassay formats including, but not limited to, Immunohistochemistry-Paraffin (IHC-P). IHC-P: 1:100-1:500. Researchers should empirically determine the suitability of the STN1 obfc1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "OBFC1, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
