General annotation (Comments)

Function	RNA-binding protein which may be involved in spermatogenesis. Required for sperm development, possibly by participating in pre-mRNA splicing in the testis.
Subunit structure	Interacts with splicing factor proteins SFRS3/SRP20, TRA2B/SFRS10, KHDRBS1/SAM68 and KHDRBS3.
Subcellular location	Nucleus.
Tissue specificity	Testis-specific.
Developmental stage	Expressed in all of the transcriptionally active stages of germ cell development from spermatogonia through spermatocytes to round spermatids.
Miscellaneous	The RBMY1 proteins are encoded by strongly repeated regions of the Y chromosome, mostly within the AZFb region. The exact number of functional copies is unclear and may vary between individues, and some of them may represent pseudogenes. The proteins are very similar, which gives their indidual characterization difficult. Thus, most experiments do not discriminate between the different members. One can therefore suppose that reported interactions with a RBMY1 protein involve all the proteins.
Sequence similarities	Contains 1 RRM (RNA recognition motif) domain.
