these data provide the evidence that membrane-bound and secretory isoforms of perforin-2 are present in human macrophages and may play important roles in immune defense
Title: Regulation of expression and trafficking of perforin-2 by LPS and TNF-α.
Collectively, these studies further underscore the biological significance of Perforin-2 and elucidate critical molecular events that culminate in Perforin-2-dependent killing of both intracellular and extracellular, cell-adherent bacteria.

Title: Perforin-2/Mpeg1 and other pore-forming proteins throughout evolution.
Knockdown of perforin-2 in macrophages did not alter the invasion of host cells but did result in chlamydial growth that closely mirrored that detected in HeLa cells.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
