Associates with the telomerase complex at sites of active telomere processing and positively regulates telomere elongation. Important for TERT binding to chromatin, indicating a role in recruitment of the telomerase complex to telomeres. Also plays a role in the alternative lengthening of telomeres (ALT) pathway in telomerase-negative cells where it promotes formation and/or maintenance of ALT-associated promyelocytic leukemia bodies (APBs). Enhances formation of telomere C-circles in ALT cells, suggesting a possible role in telomere recombination. Might also be involved in the DNA damage response at telomeres"],"length":443,"sequence":"MLSSFPVVLLETMSHYTDEPRFTIEQIDLLQRLRRTGMTKHEILHALETLDRLDQEHSDKFGRRSSYGGSSYGNSTNNVPASSSTATASTQTQHSGMSPSPSNSYDTSPQPCTTNQNGRENSERLSTSNGKMSPTRYHANSMGQRSYSFEASEEDLDVDDKVEELMRRDSSVIKEEIKAFLANRRISQAVVAQVTGISQSRISHWLLQQGSDLSEQKKRAFYRWYQLEKTNPGATLSMRPAPIPIEDPEWRQTPPPVSATSGTFRLRRGSRFTWRKECLAVMESYFNENQYPDEAKREEIANACNAVIQKPGKKLSDLERVTSLKVYNWFANRRKEIKRRANIAAILESHGIDVQSPGGHSNSDDVDGNDYSEQDTWQVRNGEEEEGRSSEGGREAEKDDSTSHSDHQDPISLAVEMAAVNHTILALARQGANEIKTEALDDD","proteome":"UP001652641","gene":"HMBOX1","go_terms":[{"identifier":"GO:0003677","name":"DNA binding","category":{"code":"F","name":"molecular_function"}},{"identifier":"GO:0003691","name":"double-stranded telomeric DNA binding","category":{"code":"F","name":"molecular_function"}},{"identifier":"GO:0045893","name":"positive regulation of DNA-templated transcription","category":{"code":"P","name":"biological_process"}},{"identifier":"GO:0005634","name":"nucleus","category":{"code":"C","name":"cellular_component"}}],"protein_evidence":4,"source_database":"unreviewed","is_fragment":false,"in_alphafold":true,"in_bfvd":false,"ida_accession":"189565d56be6cb077c096c83fd16513ead95b2a7","counters":{"domain_architectures":2311,"entries":21,"isoforms":0,"proteomes":1,"sets":3,"structures":0,"taxa":1,"dbEntries":{"profile":3,"cathgene3d":2,"ssf":2,"cdd":2,"smart":1,"pfam":2,"panther":1,"interpro":8},"proteome":1,"taxonomy":1,"similar_proteins":2311}}}
