Viral entry into host cells requires a coordinated interaction between viral and host proteins. However, the specific cellular receptors and co-receptors facilitating BCoV entry remain poorly understood. Similarly, the roles of host proteases such as Furin, TMPRSS2, and Cathepsin-L (CTS-L), known to assist in the replication of other coronaviruses, have not been extensively explored for BCoV. This study aims to identify novel BCoV receptors and host proteases that modulate viral replication and tissue tropism. Bovine cell lines were infected with BCoV isolates from enteric and respiratory origins, and the host cell gene expression profiles post-infection were analyzed using next-generation sequencing (NGS). Differentially expressed genes encoding potential receptors and proteases were further assessed using in-silico prediction and molecular docking analysis. These analyses focused on known coronavirus receptors, including ACE2, NRP1, DPP4, APN, AXL, and CEACAM1, to identify their potential roles in BCoV infection. Validation of these findings was performed using the qRT-PCR assays targeting individual genes. We confirmed the gene expression profiles of these receptors and enzymes in some BCoV (+\/\u2212) lung tissues. Results revealed high binding affinities of 9-O-acetylated sialic acid and NRP1 to BCoV spike (S) and hemagglutinin-esterase (HE) proteins compared to ACE2, DPP4, and CEACAM1. Additionally, Furin and TMPRSS2 were predicted to interact with the BCoV-S polybasic cleavage site (RRSRR|A), suggesting their roles in S glycoprotein activation. This is the first study to explore the interactions of BCoV with multiple host receptors and proteases. Functional studies are recommended to confirm their roles in BCoV infection and replication.<\/jats:p>","DOI":"10.3390\/ijms26031328","type":"journal-article","created":{"date-parts":[[2025,2,4]],"date-time":"2025-02-04T10:57:53Z","timestamp":1738666673000},"page":"1328","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Leveraging Artificial Intelligence and Gene Expression Analysis to Identify Some Potential Bovine Coronavirus (BCoV) Receptors and Host Cell Enzymes Potentially Involved in the Viral Replication and Tissue Tropism"],"prefix":"10.3390","volume":"26","author":[{"given":"Mohd Yasir","family":"Khan","sequence":"first","affiliation":[{"name":"Department of Computer Science, College of Digital Engineering and Artificial Intelligence, Long Island University, Brooklyn, NY 11201, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abid Ullah","family":"Shah","sequence":"additional","affiliation":[{"name":"Department of Veterinary Biomedical Sciences, College of Veterinary Medicine, Long Island University, 720 Northern Boulevard, Brookville, NY 11548, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nithyadevi","family":"Duraisamy","sequence":"additional","affiliation":[{"name":"Department of Computer Science, College of Digital Engineering and Artificial Intelligence, Long Island University, Brooklyn, NY 11201, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reda Nacif","family":"ElAlaoui","sequence":"additional","affiliation":[{"name":"Department of Computer Science, College of Digital Engineering and Artificial Intelligence, Long Island University, Brooklyn, NY 11201, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammed","family":"Cherkaoui","sequence":"additional","affiliation":[{"name":"Department of Computer Science, College of Digital Engineering and Artificial Intelligence, Long Island University, Brooklyn, NY 11201, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5986-7237","authenticated-orcid":false,"given":"Maged Gomaa","family":"Hemida","sequence":"additional","affiliation":[{"name":"Department of Veterinary Biomedical Sciences, College of Veterinary Medicine, Long Island University, 720 Northern Boulevard, Brookville, NY 11548, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"193","DOI":"10.1016\/S0065-3527(06)66005-3","article-title":"The molecular biology of coronaviruses","volume":"66","author":"Masters","year":"2006","journal-title":"Adv.
