Snx32 is a member of the sorting nexin (SNX)-BAR family, containing Phox (PX) and Bin/Amphiphysin/Rvs (BAR) domains. It plays significant roles in sorting and membrane trafficking of endosomal cargoes, being involved in pathways like the lysosomal degradation pathway [1].

Silencing of Snx32 leads to defects in intracellular trafficking of the transferrin receptor (TfR) and Cation-Independent Mannose-6-Phosphate Receptor (CIMPR), as well as in neuronal differentiation [2]. In the context of African swine fever virus (ASFV) infection, silencing Snx32 promotes ASFV growth and replication, while overexpressing it has the opposite effect, with Snx32 degrading the ASFV CP204L protein via the RAB1B-dependent autophagy pathway [3]. Additionally, genetic association studies suggest Snx32 may be related to Alzheimer's disease, with its protein abundance potentially having a causal role in the disease [4,5]. In lung squamous cell carcinoma, a 6-gene signature including Snx32 was identified to construct a prognostic RiskScore survival model associated with chronic obstructive pulmonary disease (COPD), with higher RiskScore samples having a worse prognosis [6].

In summary, Snx32 is crucial for endosomal cargo sorting and trafficking. Its functional studies, especially through loss-of-function experiments, have revealed its importance in various biological processes and disease conditions such as neuronal differentiation, ASFV infection, Alzheimer's disease, and lung squamous cell carcinoma prognosis. Understanding Snx32 may provide insights into developing strategies for treating related diseases.
