Genes affected

FAM118B (HGNC:26110): (family with sequence similarity 118 member B) Enables identical protein binding activity. Predicted to be involved in Cajal body organization. Predicted to be located in Cajal body. [provided by Alliance of Genome Resources, Apr 2022]

FAM118B links:

SRPRA (HGNC:11307): (SRP receptor subunit alpha) The gene encodes a subunit of the endoplasmic reticulum signal recognition particle receptor that, in conjunction with the signal recognition particle, is involved in the targeting and translocation of signal sequence tagged secretory and membrane proteins across the endoplasmic reticulum. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2010]
