Role of non-receptor protein tyrosine kinases in spermatid transport during spermatogenesis.

•Spermatid transport during the epithelial cycle is crucial to spermatogenesis.•Ectoplasmic specialization (ES) is the cellular structure that confers spermatid transport.•Spatiotemporal expression of protein kinases and actin binding proteins during spermatogenesis regulates re-organization of microfilaments at the ES.•A model depicting the role of protein kinases and actin binding proteins in spermatid transport.
