LOC100420895 Gene

fibrous sheath-interacting protein 2 pseudogene

LOC100130684 Gene

fibrous sheath-interacting protein 2-like

FSIP2 Gene

fibrous sheath interacting protein 2

This gene encodes a protein associated with the sperm fibrous sheath. Genes encoding most of the fibrous-sheath associated proteins genes are transcribed only during the postmeiotic period of spermatogenesis. The protein encoded by this gene is specific to spermatogenic cells. Copy number variation in this gene may be associated with testicular germ cell tumors. Pseudogenes associated with this gene are reported on chromosomes 2 and X. [provided by RefSeq, Aug 2016]

FSIP1 Gene

fibrous sheath interacting protein 1

Predicted to act upstream of or within several processes, including axoneme assembly; homeostasis of number of cells within a tissue; and vesicle organization. Predicted to be active in acrosomal vesicle; nucleus; and sperm head. [provided by Alliance of Genome Resources, Mar 2025]

MISFA Gene

mitochondrial sheath formation associated

Predicted to be involved in sperm mitochondrial sheath assembly. Predicted to be located in mitochondrial outer membrane. [provided by Alliance of Genome Resources, Mar 2025]
