Srpra, the signal recognition particle receptor alpha, is a key constituent of the mammalian cotranslational targeting machinery. It is involved in protein processing, intracellular trafficking, and homeostasis, which are crucial for the differentiation of neutrophil granulocytes [1]. It may also be associated with pathways like apoptosis, chaperon-related processes, unfolded protein response, cell adhesion, and cellular stress [2].

In a study on severe congenital neutropenia, genetic defects in SRPRA were discovered, leading to distinctive proteome changes in neutrophil granulocytes. By using in vitro differentiation of human induced pluripotent stem cells and in vivo zebrafish models, the effects of SRP deficiency (including that related to Srpra) on neutrophil granulocyte development were studied, highlighting the importance of Srpra-dependent processes in this cell differentiation [1].

In a study on keratoconus, genes including Srpra, whose expression in the corneal epithelium was correlated with eye-rubbing manner, were enriched in several key pathways, suggesting Srpra's potential role in the cellular response to mechanical corneal trauma [2].

In a study on bronchopulmonary dysplasia, Srpra was identified as a key hub gene, with related genes involved in pathways such as Golgi vesicle transport, which may be associated with the pathological process of BPD [3].

In conclusion, Srpra plays essential roles in protein-related cellular processes, especially in neutrophil granulocyte differentiation. Studies using various models have also implicated its role in diseases like severe congenital neutropenia, keratoconus, and bronchopulmonary dysplasia. These model-based research findings help us understand the biological functions of Srpra and its potential significance in disease mechanisms.
