Cav-p60, a specific and ubiquitous caveolar protein, was[…]identified as similar to a GeneBank entry annotated mouse polymerase transcript release factor (PTRF)[…]The results show that in a large number of cell types, PTRF is essentially located to caveolae, and that each caveola harbors many copies of the protein. Consequently, we suggest the name Cavin [sic – not capitalised elsewhere in the article] for this protein.
.

The observation that lipid rafts and caveolae were highly enriched in PS in the cytoplasmic leaflet of the membrane (Pike et al. 2002) nicely dovetails with recent findings that all cavin proteins that are required for caveola biogenesis bind PS.

2011, Ivan R. Nabi, Cellular Domains, page 46:

The cavin family consists of four proteins now termed cavins 1e4 and encoded by the PTRF, SDPR, SRBC, and MURC genes, respectively. Interestingly, none of the early studies about each cavin charcterized it as a caveolar protein.

2015, Kwang W. Jeon, International Review of Cell and Molecular Biology, page 238:

The cavin family of proteins is composed of four main types—cavin 1 (polymerase 1 and transcript release factor, PTRF), cavin 2 (serum deprivation response protein, SDPR), cavin 3 (protein kinase-c delta binding protein, PRKCDBP), and cavin 4 (muscle restricted coiled protein, MURC).

vitellary

en-adj

vitellary (comparative more vitellary, superlative most vitellary)

more vitellary (comparative)
most vitellary (superlative)

From Latin vitellus (“a little calf, the yolk of an egg”) + -ary.

af

The intestine makes several turns outside of the umbilicus, and continues in communication with the vitellary sac by means of the vitellary duct; upon the inner surface of the vitellary sac, and over the tortuous veins, membranous productions — puckered or wrinkled folds — make their appearance;

1841, Rudolph Wagner, Elements of Physiology, page 125:

The gelatinous-looking investment which, as above seen, the ovum in the Fallopian tube presents in addition to the vitellary membrane (zona) of the ovarian ovum, was first indicated by the author of this report as the future chorion.

1843 October, T. Wharton Jones, “Report on the Ovum of Man and the Mammifera, Before and After Fecundation”, in The British and Foreign Medical Review or Quarterly Journal, volume 16., page 553:

I shall here offer the remark, that if the concave superficies of the ovisac, or inner concentric, is really charged with the office of producing or excreting the vitellary matter of the ovulum, which must be admitted, even if we allow to that body the metabolic and plastic cell-force, (for it must, at least, be the producer of the cytoblatem of the cell,) there is no very great difficulty in admitting that the convex or exterior superficies of the same membrane may exercise the same functions as the dominant of those elective affinities which must be supposed as to every vital excrete.

1852, Charles Delucena Meigs, Obstetrics: the science and the art, page 126:

Vitellary degeneration is recognizable as early as 4 days after injection of HCG.

1973, Hormone Research - Volume 3, page 7:


vitellary

It is the Opinion of most, and that no without great Probability, that all the Eggs a Hen will ever lay, are contain'd in this Vitellary or Cluster, and that as soon as this Number is exhausted, she will become effœte or barren.

1879, John Moore, William Bernhard Tegetmeier, Moore's Columbarium, page 9:

A greater difficulty, in the doctrine of eggs, is, how the sperm of the cock prolificates and makes the oval conception fruitful, or how it attaineth unto every egg, since the vitellary or place of the yolk is very high; since the ovary or part where the white involveth it, is in the second region of the matrix, which is somewhat long and inverted; since also a cock will in one day fertilate the whole racemation or cluster of eggs, which are not excluded in many weeks after.

1884, Sir Thomas Browne, Simon Wilkin, The Works of Sir Thomas Browne, page 373:

Highmore also controverted the idea of Fabricius that the cicatricula is a scar left by "breaking of the footstock, by which it was fastened to the Hen," and added, "Parisanus though it the seed of the cock, but I think it to be the seminal Atomes derived from both" the cock and hen for it is already present "when the eggs are but small little grains contained in the Egg-bag or Vitellary."

1914, “The Foundations of Morphologic Embryology”, in Pamphlets on Biology: Kofoid collection - Volume 1308, page 137:

Caloricity of the body of B. rubens was determine in preovigerous females, aged>24 h, in which it is probably higher (due to the development of ovary and vitellary), than in the precedent period of growth.

parablast

The study of the relations of the' wall in the chick induced him to think that the elements of the white yolk he came parablast cells; moreover, the study of the hen's ovary led him to the conclusion that the white yolk was developed from the granulosa cells, and that these cells arise from leucocytes.

1876, Emmanuel Le Maout, Joseph Decaisne, A General System of Botany, page 950:

The scleroid patches, when present, took no part in the reaction. No new scleroid tissue was produced.

1911, William Randolph Taylor, “On the Production of New Cell Formations in Plants”, in Contributions from the Botanical Laboratory of the University of Pennsylvania, page 290:
