{"product_id":"abm216158","title":"Human Cst Complex Subunit Stn1, OBFC1 ELISA Kit","description":"\u003ch3\u003eBackground\u003c\/h3\u003e\u003cp\u003eComponent of the CST complex proposed to act as a specialized replication factor promoting DNA replication under conditions of replication stress or natural replication barriers such as the telomere duplex. 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. Initially the CST complex has been proposed to protect telomeres from DNA degradation (PubMed:19854130). However, the CST complex has been shown to be involved in several aspects of telomere replication. The CST complex inhibits telomerase and is involved in telomere length homeostasis; it is proposed to bind to newly telomerase-synthesized 3' overhangs and to terminate telomerase action implicating the association with the ACD:POT1 complex thus interfering with its telomerase stimulation activity. The CST complex is also proposed to be involved in fill-in synthesis of the telomeric C-strand probably implicating recruitment and activation of DNA polymerase alpha (PubMed:22964711, PubMed:22763445). The CST complex facilitates recovery from many forms of exogenous DNA damage; seems to be involved in the re-initiation of DNA replication at repaired forks and\/or dormant origins (PubMed:25483097). Required for efficicient replication of the duplex region of the telomere. Promotes efficient replication of lagging-strand telomeres (PubMed:22863775, PubMed:22964711). Promotes general replication start following replication-fork stalling implicating new origin firing (PubMed:22863775). May be in involved in C-strand fill-in during late S\/G2 phase independent of its role in telomere duplex replication (PubMed:23142664). 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.\u003c\/p\u003e","brand":"BT LAB","offers":[{"title":"48T","offer_id":57662032019796,"sku":"ABM216158","price":205.0,"currency_code":"GBP","in_stock":true},{"title":"96T","offer_id":57662032052564,"sku":"ABM216159","price":293.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1040\/1782\/2036\/files\/btlab-d8ed643496ec3056b661cd861a31ca020ac29593aea5b3c6c90d8cb5633ec934.jpg?v=1792159245","url":"https:\/\/www.abmium.com\/products\/abm216158","provider":"ABMIUM","version":"1.0","type":"link"}
