Fig. 5. SYCE1 and CESC1 reproduce SYCP1 localisation in Sycp3/ spermatocytes. (A-C) SYCE1 (B) distribution in mutant spermatocytes show the same altered distribution as SYCP1 (A), displaying gaps (arrowheads) along the chromosome axes. (C) Merged images of SYCE1 and SYCP1 signals. (D-F) CESC1 (E) also exhibits gaps (arrowheads) along chromosome axis, colocalising fully with SYCP1 (D). (F) Merged images of CESC1 and SYCP1 signals. Insets show gaps resulting from the absence of SYCP1, SYCE1 and CESC1.
