Gene : AtPOT1a A. thaliana

Gene ID  ? AT2G05210
Brief Description  Nucleic acid-binding, OB-fold-like protein  Source: Araport11 (06/2016).
Is Obsolete?  false
Computational Description  ? Protection of Telomeres 1a (AtPOT1a); CONTAINS InterPro DOMAIN/s: Nucleic acid-binding, OB-fold-like (InterPro:IPR016027), Nucleic acid-binding, OB-fold (InterPro:IPR012340), Telomere end binding protein (InterPro:IPR011564); BEST Arabidopsis thaliana protein match is: Nucleic acid-binding, OB-fold-like protein (TAIR:AT5G06310.1).  Source: TAIR, Jun 30, 2015.
Curator Summary  ? Encodes AtPOT1a, an accessory factor for telomerase required for positive telomere length regulation. Note on nomenclature: different names have been given to Arabidopsis POT-like genes (Kuchar and Fajkus, 2004; Shakirov et al, 2005; Tani and Murata, 2005). According to a unifying nomenclature (Surovtseva et al, 2007), At2g05210 (previously named AtPOT1) is designated AtPOT1a, while At5g06310 (previously named AtPOT2) is designated AtPOT1b.  Source: TAIR, Jun 30, 2015.

Annotation PubMed Id
AtPot1 (protection of telomeres 1) and AtPot2 are ubiquitously expressed at low levels in Arabidopsis. AtPot1 is essential for telomere length maintenance. [Atpot1] 16107718
Single-strand telomeric DNA binding activity present in A. thaliana nuclear extracts is not dependent on POT1a or POT1b proteins. 19228335
POT1a promotes an extendable telomere state via contacts with the telomerase RNP as well as STN1 and CTC1, while TEN1 opposes these functions. 25329641
Our results reveal a molecular mechanism for the role of these positively selected sites in AtPOT1a. 25697340
