There is no coding region analogous to nef in BIV.

We further examined whether HIV-nef alleles in HIV-PH subjects have signature sequences associated with the disease phenotype.

One of those mentioned is a nef.

Only proviral forms with nef deletions were revealed by length polymorphism analysis in samples from all three time points.

We found that HIV-1 nef was necessary and sufficient for proliferation of podocytes and down-regulation of synaptopodin and CALLA.
