SNHG15 aids SARS-CoV-2 entry via RABL2A

Angiotensin-converting enzyme 2 (ACE2) and several proteins have been identified as entry factors for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, whether long noncoding RNAs are involved in SARS-CoV-2 entry remains unknown. In this study, we investigated the role of small...

Sumario:Angiotensin-converting enzyme 2 (ACE2) and several proteins have been identified as entry factors for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, whether long noncoding RNAs are involved in SARS-CoV-2 entry remains unknown. In this study, we investigated the role of small nucleolar RNA host gene 15 (SNHG15) in SARS-CoV-2 entry using a SARS-CoV-2 spike pseudotyped lentivirus with a luciferase reporter. Overexpression of SNHG15 promoted but SNHG15 knockdown limited SARS-CoV-2 entry in a dose- and time-dependent manner. SNHG15 interacted with Rab-like protein 2A (RABL2A). Overexpression and knockdown of RABL2A produced similar effects on SARS-CoV-2 entry as those of SNHG15. Furthermore, RABL2A knockdown abolished the SNHG15-mediated increase in SARS-CoV-2 entry. In conclusion, SNHG15 is a critical regulatory factor that aids SARS-CoV-2 entry through RABL2A.
