HAL1 (DF0000154)

L1 retrotransposon, HAL1 subfamily

Description

HAL1 resembles half of a LINE1 element, as it encoded a protein closely related to LINE1 ORF1, but has no similarity to ORF2. The HAL1 3' end (position ~2300-2510) matches 3' UTRs of the oldest L1 subfamilies. The precise relationship between HAL1 and L1's is unresolved.
