H2bl1, details about its aliases are not provided in the given reference. It is likely related to histone-associated functions as it may be involved in chromatin regulation processes [1]. Histones play crucial roles in packaging DNA into chromatin, which impacts gene expression and various cellular processes.

However, the provided reference is about α -synuclein's role as a histone chaperone and its interaction with histone complexes like H2a-H2b and (H3-H4)2, and there is no information regarding H2bl1 in this reference.

In conclusion, without relevant information from the reference, the specific biological functions of H2bl1 remain unclear. But given its potential histone-related nature, further research using gene knockout (KO) or conditional knockout (CKO) mouse models could potentially reveal its functions in chromatin-related biological processes and associated diseases.
