Expressed primarily in the acrosome of spermatozoa and spermatids, its levels parallel the spermatogenic capacity, indicating a fundamental role in sperm development. Functional analysis using Iqcf1‐knockout mice revealed that the loss of IQCF1 leads to significantly reduced sperm motility and impaired acrosome reaction, which correlates with decreased fertility. Additionally, IQCF1’s interaction with calmodulin implicates it in the regulation of tyrosine phosphorylation of sperm proteins during capacitation, a key biochemical event that primes sperm for successful fertilization."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n"}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "P Fang, W Xu, D Li, et al.
