HMBOX1 tissues
HMBOX1 [ENSP00000430110]
Homeobox-containing protein 1; Binds directly to 5'-TTAGGG-3' repeats in telomeric DNA . 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 (By similarity). 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 .
Synonyms: HMBOX1, HMBOX1p, hHMBOX1, E5RGZ2, E5RHH9 ...
