Abstract:
This consensus was reconstructed from human DNA. This family was preserved since the pre-mammalian era and is present in >100 detectable copies phg. This sequence can be easily expanded by ~200 bp (not included). The 5' expansion is very purine-rich and resembles simple sequences. It matches thousands of genomic sites which are very non-evenly distributed over different chromosomes. Therefore it cannot be excluded that this LINE fragment is a part of a SINE-like element. The translated sequence matches CR1-like sequences from chicken and turtles, as well as HER1_ST LINE from sharks.
